Hi…

Try giving This for your URL in the navigate to activity
WorkItemID.ToString

This will convert the value in workitemid to string format in where you set the URL

[balkishan (Balkishan Singh)]

that way it’s accepting but why it’s not accepting without using .ToString.
In pdf walkthrough they didn’t convert into string.

[Lahiru.Fernando]

For that, that variable should be in GenericType.

You can change the data type to generic and use it without.ToString

Generic types can hold any data type. And will convert them automatically to the required format
