I'm creating two custom screens within the Ticketing Setup -> Production Elements -> Title area.
In order to be able to link a data row from the first custom screen to a data row in the second custom screen I'm using a dropdowndatawindow on the second screen which lists a piece of data from the first screen's table, and then stores the id_key value as the link. Both screens and the DDDW is based on inv_no so the DDDW should list the values already saved on the first screen as options for the second screen.
However I'm getting an Infomaker style prompt to enter the inv_no parameter value, before the second screen has rendered.
It's as if the DDDW doesn't know the inv_no at runtime. If I manually provide the correct inv_no then it will propulate the dropdown correctly. If I don't enter a value (effectively submitting a NULL inv_no) then the dropdown is empty.
Seeing as both of the screens know's what their inv_no is, why doesn't the DDDW know what the inv_no is?
And if anyone has a better method of linking two custom screens together rather than this DDDW then I'd appreciate your suggestions to that!
Thanks
