If I am trying to add any collection as a inputs/outputs parameter or in Code and after click on "code check" button. It always gives error. Let me know the reason. In case if I am doing something wrong then please suggest the reason and share any running sample using collection/DataTable in Code stage Thanks Ratan Sen Thu, 09 Mar 2017 21:09:00 GMT https://community.blueprism.com/t5/Product-Forum/Using-DataTable-Collection-in-Code-stage/m-p/84916#M35983 Ratan_SenChaud1 2017-03-09T21:09:00Z https://community.blueprism.com/t5/Product-Forum/Using-DataTable-Collection-in-Code-stage/m-p/84917#M35984 Look in the Utility - Collection Manipulation object for examples Mon, 13 Mar 2017 13:22:00 GMT https://community.blueprism.com/t5/Product-Forum/Using-DataTable-Collection-in-Code-stage/m-p/84917#M35984 John__Carter 2017-03-13T13:22:00Z https://community.blueprism.com/t5/Product-Forum/Using-DataTable-Collection-in-Code-stage/m-p/84918#M35985 May beyou havent added allthe resources and namespaces,I was getting the same.
