Conquering the Frustrating “Invalid Procedure Call or Argument (Error 5)” in VBA Macro Excel: A Step-by-Step Guide

Are you tired of encountering the dreaded “Invalid Procedure Call or Argument (Error 5)” in your VBA macro Excel project? Don’t worry, you’re not alone! This infuriating error can strike even the most seasoned Excel gurus, leaving them staring at their screens in frustration. But fear not, dear reader, for we’re about to embark on a mission to vanquish this error once and for all!

What is the “Invalid Procedure Call or Argument (Error 5)” Error?

The “Invalid Procedure Call or Argument (Error 5)” is a runtime error that occurs when your VBA macro attempts to execute an invalid procedure or passes an incorrect argument to a function. This error can manifest in various ways, such as:

• When you try to call a procedure that doesn’t exist or is misspelled
• When you pass an argument of the wrong data type to a function
• When you try to access an object or property that doesn’t exist
• When you have a syntax error in your code

Common Scenarios that Trigger the Error 5

In this section, we’ll explore some common scenarios that might lead to the “Invalid Procedure Call or Argument (Error 5)” error:

Scenario 1: Typo in Procedure Name

Sometimes, a simple typo in the procedure name can trigger the Error 5. For instance:

Sub MyMacro()
    Call MyMacr0  ' Note the 0 instead of o
End Sub

In this example, the procedure name “MyMacr0” doesn’t exist, resulting in the Error 5.

Scenario 2: Incorrect Argument Data Type

When you pass an argument of the wrong data type to a function, you might encounter the Error 5. For example:

Sub MyMacro()
    Dim strName As String
    strName = "John"
    MsgBox Len(strName, 5)  ' Incorrect argument data type
End Sub

In this case, the Len function expects a single argument, but we’re passing two arguments, resulting in the Error 5.

Scenario 3: Accessing Non-Existing Object or Property

Trying to access an object or property that doesn’t exist can also trigger the Error 5:

Sub MyMacro()
    Dim ws As Worksheet
    Set ws = ThisWorkbook.Worksheets("NonExistingSheet")
    MsgBox ws.Cells(1, 1).Value  ' Error 5 because the sheet doesn't exist
End Sub

In this example, we’re trying to access a non-existing worksheet, resulting in the Error 5.

Troubleshooting and Fixing the Error 5

Now that we’ve explored the common scenarios that lead to the “Invalid Procedure Call or Argument (Error 5)”, let’s dive into the troubleshooting and fixing process:

Step 1: Review Your Code

The first step is to meticulously review your code, line by line, to identify any potential errors or typos. Check for:

• Typos in procedure names, variable names, and function calls
• Incorrect data types or argument mismatch
• Uninitialized or undeclared variables
• Syntax errors or missing brackets/parentheses

Step 2: Use the Debugger

The VBA debugger is an incredibly powerful tool that can help you pinpoint the error. To use the debugger:

1. Open the Visual Basic Editor (VBE) by pressing Alt + F11 or navigating to Developer > Visual Basic
2. Click on the “Debug” menu and select “Step Into” (F8) or “Step Over” (F5) to execute your code line by line
3. The debugger will highlight the line of code that causes the Error 5

Step 3: Check the Error Description

When the Error 5 occurs, VBA will display an error message with a description. Take note of this description, as it can provide valuable insights into the problem:

Error 5: Invalid procedure call or argument
Module: MyModule
Procedure: MyMacro
Line: 5

In this example, the error description points to the “MyMacro” procedure in the “MyModule” module on line 5.

Step 4: Fix the Error

Once you’ve identified the problem, fix the error by:

• Correcting the typo or syntax error
• Passing the correct argument data type
• Accessing the correct object or property
• Rewriting the code to avoid the error

Scenario	Error Cause	Fix
Typo in Procedure Name	Misspelled procedure name	Correct the typo
Incorrect Argument Data Type	Passing wrong data type to a function	Pass the correct data type
Accessing Non-Existing Object or Property	Trying to access non-existing object or property	Access the correct object or property

Conclusion

In conclusion, the “Invalid Procedure Call or Argument (Error 5)” in VBA macro Excel can be frustrating, but it’s not impossible to overcome. By following the steps outlined in this guide, you’ll be well-equipped to troubleshoot and fix the error, getting your macro up and running in no time.

Remember to review your code carefully, use the debugger, and check the error description to identify the problem. With patience and practice, you’ll become a master at conquering the Error 5 and creating robust, error-free VBA macros that will make your Excel experience a breeze!
