Hello Dawndev,
This was a rather tricky filter. Because the filter applies to the main DS we must use the full xpath to the node in the main DS. Here is the filter that was on your last form:
not(. = current()/my:deviceType)
and the new:
not(. = xdXDocument:get-DOM()/my:myFields/my:InventoryInformation/my:GeneralInventory/my:deviceType)
Please find our form attached with the change.
Thanks!
Bre
