Troubleshooting Guide

Common Issues and Solutions

1. Excel Connection Problems

Symptom: Can’t connect to Excel file

Solutions:

• Ensure file is saved in OneDrive for Business or SharePoint
• Check sharing permissions on the Excel file
• Verify table name matches exactly (“TimesheetEntries”)
• Try refreshing the data connection

2. Delegation Warnings

Symptom: Blue underline warnings in formulas

Solutions:

• Use Filter() before other operations
• Replace CountRows() with First(Sort()) patterns
• Avoid complex expressions in delegation-unfriendly functions
• Use local collections for complex operations

3. Date Formatting Issues

Symptom: Dates appear incorrectly in Excel

Solutions:

• Use DateAdd() for time zone conversion
• Format Excel columns as “Date” type
• Use Text() function for display formatting
• Verify regional settings match

4. Patch Function Failures

Symptom: Data not saving to Excel

Solutions:

• Check Excel table structure matches exactly
• Verify all required fields have values
• Use Defaults() function for new records
• Test with simple Patch operations first

5. Container Layout Problems

Symptom: UI elements overlap or don’t align

Solutions:

• Set explicit Width and Height properties
• Use Parent.Width and Parent.Height correctly
• Check AlignInContainer settings
• Verify container Direction property

6. Performance Issues

Symptom: App loads slowly or becomes unresponsive

Solutions:

• Limit Filter operations
• Use collections for frequently accessed data
• Avoid complex formulas in visible properties
• Implement lazy loading for large datasets

Debug Techniques

1. Use Label controls to display variable values
2. Add trace statements with Set() functions
3. Test formulas in the formula bar
4. Check error messages in Monitor tool
5. Use simple test data to isolate issues
