That's a simple one:

Middle ( Pn_Yoke ; 2 ; 999)

Like this you start at the second character and take whatever comes behind. Hope that helps....

Thanks a lot Martin Z.

Now I need validate the prefix P on the field, but I don't know how can get it,
By example the Data entry on the field is P764-15543-001 , I need validate the first character "P" prefix if the condition are met the ned step is use middle(Pn_Yoke ; 2 ; 999)
If the condition are not met we need delete the data entry on the field.

One more time thanks four you help on this matter..

Again simple:

If ( Left ( Pn_Yoke ; 1 ) = "P" ; Middle(Pn_Yoke ; 2 ; 999) ; Pn_Yoke )

Regards,
Martin

Thanks a lot Martin


I really apreciated you time and Support on this matter.

Sorry by my questions as beginner programming on file maker.


Now I need a condition when the prefix is different of "P" delete the information entry on the field, keept the mouse cursor on the same field until the prefix is equal to "P" and also send a message error like "Invalid Prefix".

Regards.

Antonio,

In that case you're looking at a script, rather than just a Custom Function.

Create a script with the name: "Validate Pn_Yoke Field"
Enter the following in the script:

If [(not IsEmpty(db_Name::Pn_Yoke)) and (Upper(Left(db_Name::Pn_Yoke ; 1)) <> "P")]
Set Field [db_Name::Pn_Yoke ; ""]
Show Custom Dialog ["ERROR" ; "Invalid Prefix"]
Go to Field [db_Name::Pn_Yoke]
End If

Now go to the Pn_Yoke field on the layout and set up a script trigger for OnObjectExit. The trigger points to the Validate Pn_Yoke Field script.

That should do the trick. Good luck.

Regards,
Leon.
