Hide #Error on form

I have a calculated field on a form using:

=DMax("[HBA1CChecked]","Treatment","[MemberID] = " & [Forms]![frmMemberMaster]![txtMemberID])

But I get #Error when there is no record to DMax.

How can I hide the #Error  ??

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

=DMax("[HBA1CChecked]","Treatment","[MemberID] = " & Nz([Forms]![frmMemberMaster]![txtMemberID]),0)

Also, make sure that the control name does not duplicate the name of a field from the form's RecordSource.
