Have written some elementary VBA code in an excel spreadsheet with a
UserForm that shows on demand with some calculated output using some
of spreadsheets cells as input.

Please excuse my terminology, I am embarrased enough to try to even
ask.

The problem is, that I have a command button on the UserForm. I cannot
seem to get the variables in the main "sheet1" or Worksheet(?) code to
pass to the command button code for the UserForm (click event).

How can I call them up to the UserForm CommandButton code please ?

If this makes sense to anybody I'd appreciate a response.
