Well, the answer may be staring me in the face... but hey, it's Monday.
I just created a custom title block which otherwise works fine. However, when I was linking text to a record, I ran into a problem with the field type. Specifically:
Edit Field > Number > Date > Format > MDY.
When I close the "Number Format" window, return to the "Edit Field" window, and select the "Number" radio button, no matter what I type into "Name" or "Default"--the fields will not accept the data. I've typed letters, numbers, etc., but when clicking on "OK", my machine just patiently beeps at me...
Anyone have a suggestion?
