Copying variable from one form and use them to populate another form

 I am trying to copy variables from the Service Request form in Telesales and use them as bind variable to a query that populates a field in the Requisitions form in Purchasing.

I tried copy(NAME_IN('INCIDENT_TRACKING.INCIDENT_ADDRESS),'GLOBAL.INCIDENT_ADDRESS') from Service Request form; and then pass 'GLOBAL.INCIDENT_ADDRESS' to my query as a variable in another form. 'GLOBAL.INCIDENT_ADDRESS' is not being passed to Requisitions form query.

I also tried creating a package that gets the global variables and pass them over to the Requisitions form but no joy either.

xxvg_create_ir_k.create_ir (p_incident_address     => NAME_IN('INCIDENT_TRACKING.INCIDENT_ADDRESS'),
