“Parameter Name in Task” – a text field that is filled in manually from the keyboard. This field displays the text that corresponds to the value of the specified Parameter of the selected Task. The User can change this value in the text field, and after saving the form, the new value will be recorded in the specified Parameter of the selected Task.
