  5. Leave your cursor at the end of the action you just entered, and select Else from the drop-down list.
  6. Enter the action to perform if the condition is false, on the line between the Else statement and the EndIf statement.

When you enter the actions to perform, you can use the choices in the Snippets area to insert a function at the cursor location. You can then add the appropriate arguments for the function.

Note: You can also enter any of the text described in these steps manually; however, using the drop-down lists and snippets can reduce mistakes.
