Fix Excel VBA UserForm Run-Time Error 13 Type Mismatch
Question details
The user is encountering a Run-Time Error 13 (Type Mismatch) when launching an Excel VBA UserForm, despite the project compiling successfully.

- Product
- Excel VBA
- Device & OS
- not provided
- Scenario
- Launching an Excel VBA UserForm that assigns values to controls like SpinButtons and interacts with worksheet data.
- Observed behavior
- The VBA code compiles without issue, but raises Run-Time Error 13 upon execution. The error stems from attempting to assign a text string to a numeric control (SpinButton) and potential object mismatch issues in a With statement.
Open the Visual Basic Editor (Alt + F11) and click 'Debug' on the error prompt to identify the exact line of code highlighted in yellow causing the mismatch.
Correct the SpinButton Data Type Assignment
Fix the type mismatch error by ensuring numeric controls only receive numeric values, avoiding string assignments.
A common cause of Error 13 is assigning text to a control that exclusively requires numeric data. A SpinButton control expects an integer value to determine its position. Passing a string format like "0.0 - 1000" will immediately trigger a type mismatch.
In your UserForm initialization code, find the line where you assign a value to the SpinButton, such as `.SpinButtonQuantity = "0.0 - 1000"`.
Replace the text string with a valid integer. For example, change it to `.SpinButtonQuantity = 0`.
Press F5 to run the UserForm again and verify if the run-time error has been resolved.

Verify 'With' Statements and Worksheet References
Ensure that objects referenced in your code, such as forms and worksheets, are correctly defined and populated.

Frequently Asked Questions
What exactly does Run-Time Error 13 Type Mismatch mean in VBA?
This error occurs when your code attempts to assign a value of one data type to a variable or property that strictly requires a different data type, such as attempting to put text (a String) into a numeric control (like a SpinButton).
Why does my VBA project compile successfully but fail at run-time?
Compiling only checks for syntax errors and valid object references. Data type mismatches, such as pulling text from a worksheet into a numeric variable, only evaluate when the code actually runs and processes the specific data.
How do I find which line of code is triggering Error 13?
When the error dialog pops up during execution, click the 'Debug' button. The Visual Basic Editor will open and highlight the exact problematic line of code in yellow.
Does WPS Spreadsheet support Excel VBA UserForms?
Yes, WPS Spreadsheet offers robust support for VBA and macros, including editing and running UserForms, allowing you to migrate your automated Excel projects seamlessly.
