IFS formula and adding number of days

EvaL

How to convert this Excel formula into Smartsheet

=IFS(ISBLANK(C3),"",E3="Product1",C3+30,E3="Product2",C3+15, E3="Product3",C3+30,E3="Product4",C3+30)

I would appreciate your help.

Thank you:)

Try something more like this:

=IF(C3 = "", "", IF(OR(E3 = "Product1", E3 = "Product3", E3 = "Product4"), C3 + 30, IF(C3 = "Product2", C3 + 15))
