If Step
Use the If step to cause the script to go to one of two branches based on the evaluation of a specified Boolean expression.

The If step automatically adds two output branches, True and False:
-
True—Steps following this output branch execute if the expression is true.
-
False—Steps following this output branch execute if the expression is false.
To use the If customizer window to create True and False output branches, either enter an expression in the text field or click the Expression Editor (...) button to enter an expression, and then click OK.
