How to launch a request set and add parameters from the sales order form with forms personalization

Builtin: Launch a function
Function code: FND_FNDRSRUN
Parameters: SET_APPL_SHORT_NAME="XXONT" REQUEST_SET_NAME="FNDRSSUB995" CHAR1="ESF"

this is working but I would like to send information from the form to char1 :order.ship_from.

I have tested the following in the parameters but it doesn't work:

= select 'SET_APPL_SHORT_NAME="XXONT" CONCURRENT_PROGRAM_NAME="FNDRSSUB995"
CHAR1="'||${item.ORDER.SHIP_FROM.value}||'"'
from dual

Any suggestions?
