How to Troubleshoot VBA Compile Errors When Finding Unique Value Combinations in Excel
Question details
The user is trying to find unique combinations of values in Excel rows using VBA but encounters multiple compile errors after copying the script from a website.
- Product
- Excel
- Device & OS
- not provided
- Scenario
- Running a copied VBA macro to identify value combinations that do not occur together, which results in execution failures.
- Observed behavior
- The macro triggers compile errors such as 'User-defined type not defined' for Scripting.Dictionary, 'Sub or Function not defined' for ArrayBubbleSort, and syntax errors caused by extra line breaks.
Before modifying your macro code, open the VBA Editor by pressing Alt + F11 and ensure your workbook is saved as a Macro-Enabled Workbook (.xlsm).
Remove Extra Carriage Returns After Line-Continuation Characters
Fix syntax errors that occur when copying VBA code from unformatted websites.
When copying code directly from a web page, hidden formatting or extra carriage returns can be introduced. In VBA, an underscore (_) is used as a line-continuation character, and placing an empty line immediately after it breaks the code block.
In the VBA Editor, scan your pasted code for underscores (_) located at the end of code lines.
Remove any empty lines or extra spaces immediately following the underscore so that the continued code starts directly on the very next line.
Click Debug > Compile VBAProject in the top menu to verify that the syntax error has been resolved.
Resolve Missing References and Procedures
Address 'User-defined type not defined' and 'Sub or Function not defined' compile errors.

Frequently Asked Questions
Why does my VBA code fail when I copy and paste it from the internet?
Copying code from a web browser often brings hidden HTML formatting, non-breaking spaces, or extra carriage returns. These invisible characters disrupt VBA's strict line formatting rules, especially around line-continuation underscores.
What does 'User-defined type not defined' mean for Scripting.Dictionary?
This error occurs because VBA does not know what a 'Scripting.Dictionary' is by default. You must explicitly tell VBA where to find this object by enabling the 'Microsoft Scripting Runtime' reference in the Tools > References menu.
How can I extend this VBA logic to check combinations of four or five values?
Extending the logic to larger combinations requires modifying the nested loops within the VBA code to iterate through additional columns. This typically requires an understanding of advanced VBA programming and array manipulation.
