Maybe the textbox isn't actually empty, but has one or more spaces in it at this point. Perhaps your check should be more precise in demanding that some characters are input. Initialise the value of the text box to, say "" or " " (for a 4 char field). Then you can test for the value <> SPACE(4).

As Naomi said, you should return 0 or .F., but have a care for when the frustrated user wishes to abandon the update and can't get out of this field.

Why not:
IF EMPTY( This.Value)

or:

If this.value = SPACE(4)

As it is the valid clause OF the field thisform.txtEmergency_UnitNo
