topic You need to go back to the in Product Forum https://community.blueprism.com/t5/Product-Forum/Dynamic-Element-Error-in-Mainframe-system/m-p/93378#M42965 You need to go back to the Foundation training and re-read about dynamic attributes. Dynamic means 'This attribute in included in the element fingerprint but I don't want to hardcode the value in application modeller, I want to supply the value from the diagram at run time'. This means that at every point in the diagram where the element is used, you need to supply the dynamic value. In the properties of the diagram stages using the element, you'll see that a button is enabled next to the element name.

When I spy the element and if that item is dynamic in nature, I am keeping start Y and end Y as dynamic and want to look through Y axis dynamically to retrieve the items, but when I keep it as dynamic in application modeler, it doesn't accept. It gives me an error as : Stage: Read Gross Description: Missing element parameter for attribute 'StartY' in row 1 Can anyone suggest what's the possible solution for this?
