I would do a select first, I think you will find that it is easier to work with cursor to hold the report data than with individual tables.

SELECT [FieldList] FROM [Table] WHERE First_Name = "PEter Monica" INTO CURSOR C_DATA

IF RECCOUNT('C_DATA') = 0
* Show message
ELSE
REPORT FORM REPORT 1 PREVIEW NOCONSOLE
ENDIF

>report form report1 for ((app.First_name="PEter Monica")) NOCONSOLE PREVIEW))
>
>but is there a way i can do an error message or a message box in the event PEter Monica doesnt exist? like...an else? i kno the logic but im not to sure how to implement that with a report. Unless if i do a query and select every one i(in a table /cursor) want to and just do a normal report?
