Understanding the Type Mismatch Error in VBA For Loops

If you've ever worked with VBA in Excel, you might have encountered an issue known as Type Mismatch (Error 13). This error can be particularly frustrating when it occurs in loops, especially if you're new to VBA programming.

Recently, a user faced this problem in their code, specifically when trying to compare values in a for-loop. Here's what happened:

Error Trigger:
The error arose from the line:

Despite not seeing any obvious mistakes at first glance, the error persisted. Let’s break down the cause of this issue and how it can be solved effectively.

Analyzing the Code

Looking closely at the provided code, a few key variables play a crucial role:

lastrow: This variable determines how many rows to loop through.

v: This is a Variant type that stores values pulled from a specific range in one of the worksheets.

The problem originates from how these values are assigned and where they start.

The Problem: Array Size Mismatch

In the VBA code, we see that:

The range for the value v begins from row 4.

However, the assignment to wsSheet starts at row 2.

This discrepancy leads to the last two values in v being # N/A when the code tries to assign these values to the wsSheet, which ultimately results in the Type Mismatch error.

Solution: Adjusting the Code

To resolve this error, we need to ensure that the ranges align properly so that the data is correctly placed without leaving excess rows filled with # N/A.

Recommended Changes

You can modify the code snippet to avoid the # N/A issue like this:

This adjustment will ensure that you only attempt to place as many values in the range as you have in your array, thereby avoiding the Type Mismatch error.

Implementing the Fix

Here’s how your modified code snippet would look after implementing this fix:

Conclusion

Learning to navigate and fix errors like Type Mismatch can significantly improve your ability to work with VBA in Excel. By ensuring that the cell ranges and offsets in your code align properly, you can prevent such frustrating errors from occurring in the future.

Remember, debugging is a crucial part of programming, and careful attention to detail often makes all the difference!
