Hi,
Set the required property of the field, in the design table, to yes (Jet)
or uncheck Allow Null (in MS SQL Server). That will enforce the requirement
every where you use the table. If you want to enforce it only for one
particular form, follow the suggestion by TC here up (you can use the after
update event of the control too, and you can add an error message to warn
the end user that the absence of data is incorrect).
Hoping it may help,

I am trying to get the tab to stop if data is not entered into the text
box. When I enter=(is not null) I get a data error. Please advise.
