I tried this but I got an error message:
".../txtEmployeeName" does not point to a valid location path of a field or group.
What I did is using Rule dialog to insert an action (set a fields value). I tried to insert this value:
txtEmployeeName[txtEmployeeName = txtCurrentUser]
where txtEmployeeName and txtCurrentUser are fields I inserted by click on "Insert Field or Group..." button. What I did wrong?
