As a novice I've apologized for my duplicate posting...can someone now help
me to resolve my issue so I can stop wasting everyone else's time?
I suspect that the problem is because of the blank in your form name.
If any object (Form, Control, Field, tablename) contains a blank or
other special character you must, no option, enclose it in square
brackets.
Try
[Forms]![Assignable Asset Form-Tabs]![cboCategory]
ANother possible problem is that the form named [Assignable Asset
Form-Tabs] must be open as a main form (not a subform).
I don't know where in you are referring to this form control but I'd
guess it's either in a Query used as the recordsource for a form, or
used as the Rowsource for a combo box.
