I am working on a requirement in infopath but iam stuck at a something that seems really simple . I have SP list IP form that contains 3 multi-select check box ,all three containing identical values . So if item 1,2 is checked in Multi1 and 2 is checked in Multi2 then Multi3 should be populated with 1(ie: All those selected in Multi1 - Those selected in Multi2) . <br /> <br /> My approach was : I had set the source of Multi 3 to Multi 1 and set a filter /dfs:myFields/dfs:dataFields/my:SharePointListItem_RW/my:multi1/Value[. != ../../my:multi2/Value] <br /> <br /> However this does not seems to work out . For testing i edited &#39;!=&#39; to &#39;=&#39; and Multi3 populates identical values in Multi1 and 2 . <br /> <br /> Is there any issue in the delta logic I am applying ?PFA <br /> <br /> Regards, <br /> <br /> Grigory
