First, I'm curious why you are not simpy setting the dgData to an array. But that aside, what is the name of your datagrid? The error is indicating there is no group by that name on the current card. Another thing that can throw you is if the stack is opened modally. Then it's not the topStack, so relative references will be for the currentCard of the topStack.
In your button try: put getParentCard(the long id of me) into tThisCard then when you refer to your datagrid use group "dgDataDisplay" of tThisCard (assuming it's on the same card as the button) Put this handler in a library or in the script of your button: function getParentCard pObjectID put offset("card id", pObjectID) into tStartChar put char tStartChar to -1 of pObjectID into tCardID return tCardID end getParentCard Bob S > On Apr 11, 2018, at 06:53 , Ian McKnight via use-livecode > <email@example.com> wrote: > > createTabbedDataList _______________________________________________ use-livecode mailing list firstname.lastname@example.org Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
