How do I set up new variables

Hello,

How do I add a variable from customworks to ePDM? I have tryed with following settings but it doesent work

I'm trying make a new search card where there is a checkbox conected to the variable "kiinnitysosa" and if you put a check in the checkbox ePDM will search for all the parts that have been saved in customworks with a check in the same box.
