What line of code is highlighted when you choose to debug?
It could be a variable not being defined in a module with Option Explicit on.
My code was not saving the code I posted right above calling the Toolbar button.

When I name it as sugguested, I get an error when I click the button:
Cannot run the macro "Test Excel.xlsm'!ShowDateCheckerForm'. The macro may not be available in this workbook or all macros may be disabled.
