This macro is being called from a form and I am using the conditions column to test for a null value. If the combobox on my form is null, I want the msgbox to run but if there is a value in the combobox on the form, I want the macro to ignore the line: MsgBox("Do you want all sizes?",4,"Size")=7. That line is in the conditions column of the macro but it runs no matter whats in the combobox on the form. Not sure if I've explained myself properly or not. I'll try to give more information if thats not enough.
