I have created a form in Excel that is to be filled in by end users. This form spans several worksheets. On each worksheet there are several input fields that must be populated with data. (I've labelled these as required, but you know how people listen). The data that will go into these fields can be freeform alphanumeric data. I wanted to set a validation control that would prompt the end user with an error message should they try to save the workbook or navigate to another worksheet without populating all of the required fields.
Can someone please help with this validation control?
Thanks
