I'm new to InfoPath and SharePoint and i also use the trial version of qRules, i have 2 sharepoint lists, with one (let's call it "list1") having a lookup column to the second ("list2"), and this column permit multi-items selection. when i am using the default form i can add an item to "list1" with all the selected items in the lookup column separated with a semicolon. but when want to use a custom form, and a multi-checkbox, and i don't know how the selected items ID's must be submitted to the SharePoint list (i tried separating the items ID's with : ',' , ';' , '.' ; ' ' ...).
I want the selected items to be displayed like this in the lookup column :
Thank's for your help.
