Hi Henry,

"...any one one of the 3 fields in a table has data. If it does then, disable the enter Data button to allow Edits only..."

If I understand your goal, your code will not run correctly. Say mPersonalData is not empty and you disable cmdEnterData. Then you go to the next IF statement and mPastHist is empty. Here you enable cmdEnterData, but you really should leave it disabled since mPersonalData was not empty.

Here's code that is more concise and will enable the cmdEnterData button only when all three fields are empty.

THISFORM.cmdEnterData.Enabled = ;
	EMPTY(curPatientSummary.PersonData) AND ;
	EMPTY(curPatientSummary.PastHist) AND ;
	EMPTY(curPatientSummary.Allergies)

Finally, set your mUpdatePatSummary:

mUpdatePatSummary = NOT THISFORM.cmdEnterData.Enabled

>All I am trying to do here is to see if anyone one of the 3 fields in a table has data. If it does, then, disbale the enter Data button to allow Edits only. If it does not have any data, then enable Enterdata only and disable Edit. There could be situation where only one of the fields is blank - in which case it should be treated as an edit.
