I want that once the user have inserted the inputs they are used to create instances. However I also want that once the program is cancelled, nothing happens. As the workflow is, if the user cancel the program I get an obvious error on the node "get item by index", but I would like that "Get item by index" is only run if the program is not cancelled. What should I put as true on the "if" node in order to stop the program to continue running.<BR />Any help is appreciated,<BR />Thanks,<BR />Daniel</P> Fri, 07 Aug 2020 14:00:31 GMT s258085 2020-08-07T14:00:31Z https://forums.autodesk.com/t5/revit-api-forum/dynamo-problem-data-shapes/m-p/9679144#M32627 <P>Hello everyone, my first post over here <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span></P><P><BR />Im working with dynamo for about one week but I still cannot resolve this.</P><P>Im creating a user interface with data shapes.
