Steven,

Typically, we've added code to the method used to test for uniqueness:

LPARAMETERS tcAgencyName
LOCAL llRetVal, lcRule

lcRule = 'Your error message text'
llRetVal = .T.

*Of course, we're assuming your alias is buffered here!!
IF INLIST(GETFLDSTATE("AgencyName", YourAliasName), 2, 4))
   **Do your test here against tcAgencyName value and set llRetVal = .F. if it's not unique.
ENDIF

IF llRetVal
   This.ClearBrokenRule(lcRule)
ELSE
   This.AddBrokenRule(lcRule)
ENDIF

RETURN llRetVal

Hope that helps,

The whole checkrules thing fires if a change is made anywhere on the form, even if the txtAgencyName is not entered or changed. It obviously is not able to determine if the value in the txtAgencyName is the same as the original value. What am I missing? Thanks in advance for any comments.
