Whoever gave you the idea it should?  You want to use progn here, not
lambda.

Actually, you don't need to use even progn here: everything beyond
the first clause of an if-form belong to the else-part.

Please start using C-h f on functions/forms you have no clue about.
Better yet, read an introduction to Lisp.
