Default TextBox reads entry as numeric instead of text

I have table tblPatients with the following fields:
PatientIDNum (Autonumber)
PatientNameLast (Text)
PatientNameFirst (Text)
PatientMRNum (Text)

Field PatientMRNum is a 7 character medical record number each character of
which is incidently a numeric character.

I have a form with TextBox txtIDNum in which users the patient's MRNum
number. A command button on the form has the following code:

MsgBox "Is patient " & DLookup("PatientNameLast", "tblPatients",
"PatientMRNum=" & txtPatientMRNum) & " the patient whose chart you're
reviewing?"

Unfortunately, DLookup apparently thinks the contents of txtPatientMRNum are
integers because this code generates a data mismatch error. The code WILL
work perfectly if I change the datatype of PatientMRNum in tblPatients to
Number (but I don't want to do this).

Is there a way to get the txtMRNum to interpret the entry as a simple text
instead of a numeric?

Thanks in advance!

John

Actually, since you're not telling DLookup that PatientMRNum is text, Access
thinks you mean it's a number, and then it chokes on it! That's why you're
getting the type mismatch.

If you want Access to treat what's in [txtPatientMRNum] as text, you'll need
to add quotes around it.
