Question : How to get a message box to Count records?

I am making a WMS label tracking application where a picker scans their id badge and then the labels they have to go pick.

I need a message box to appear off of a button that says they have scanned so many labels and do they have anymore labels to scan.  If yes then the close message box.  But when no is entered I need the code to run a macro

The count would be done on a field named PickerID
