Web Designer Error on Adding Function Mapping

Hi All,

I created a function mapping under a component reference inside VI_ITShop_ApprovalItem.When I tried to compile, I got the following error: "There is no cursor with index 1 defined on the collection PWOToDecide." arising from the VI_ITShop_Approval_Item node in the VZW_ITShop_Approvals module. Anyone know why? Please see the screenshots below:

Thanks in advance,
