[Excel 2003]

I have command buttons on the userform which access other userforms (which
drive the spreadsheet data entry)

I have a listbox on the userform displaying a number.

I would like to enter code into the command button activations such that if
the number in the listbox does not equal the number stored within the code
of the command button then a mesage box is displayed and the command button
does not activate its sub routines.

Can anyone help?

Thanks,

Roger
