Filter planning sequences by tranfering WAD listbox values

Hi Gurus,

We have created an IP model by using the Web Application Designer.We have created listboxs and buttons that execute planning sequences but we don't find the way to filter the data that the functions manage by tranfering the value that is currently selected in the listbox.

We have tried all the Data Binding options of the command EXECUTE_PLANNING_SEQUENCE_SIMPLE.

Does exist any way to transfer a value of the listbox to a planning sequence.

Thanks in advance,

Joan Guillen.
