I use exactly the same code as you showed me. Here is my valid method :

IF EMPTY( this.value)
RETURN 0
ENDIF
IF NOT EMPTY( this.value)
SELECT othertable
SET ORDER TO key1
IF NOT SEEK( this.value)
MESSAGEBOX(' Item NOT FOUND !',48,'')
RETURN 0
ENDIF
ENDIF

But VFP 5.0 seems to ignore the "IF EMPTY(this.value)" but VFP 5.0 still responds to the "IF NOT EMPTY( this.value)".

Finally, I copy the grid to another temporary form and then I put a new grid on the current form's pageframe (still on page2) and copy all methods from the old grid which is on the temporary form and set the grid's appearance to look the same as the old one and it works. But I still do not know the reason why my old grid does not work.

Could you please tell me why ?

Thanks,

>Andi, could you give us the code in the valid method? You SHOULD be able to use code like:
