Andi, sometimes code fails because of extra characters, and sometimes for other reasons. I usually try to set a local variable to 'this.value' and then use that variable.

Also, check with the debugger to see if 'this.value' is truly empty. Is it NULL? 0? What type is it? This could solve the problem, because the value was set to something other than totally blank before you entered the textbox.

Sorry I can't be more explicit.

But I still do not know the reason why my old grid does not work.

>>Andi, could you give us the code in the valid method? You SHOULD be able to use code like:
>>
>>If empty(this.value)
>> ** your code here
