The If Step
Continue the aa.aef script by dragging an If step from the General palette to the Design pane, and dropping it over the Call Redirect step, as shown in figure End of Script.
Configure the If step to determine whether or not the maximum number of retries has been reached. As in the previous examples, the If step and Increment step allow the caller the maximum number of retries.
If the transfer is successful, the script ends.
