how to add an OR statement to formula

RenPNW,

Formula suggested by Rob_Elliott should work for you.

However, And and Or function already returns true/false result. Hence, no need to use If function. Use shorter formula like: 

varTabSelected=1 && (DataCardValue71.Selected.Value = "Diversion" || DataCardValue72.Selected.Value = "Diversion")

OR 

And(varTabSelected=1, Or(DataCardValue71.Selected.Value = "Diversion", DataCardValue72.Selected.Value = "Diversion"))
