I am trying without much success to find the correct formula expression to resolve the following:-

IF <Value from Picklist field> = 5   then return 35 as value

IF <Value from Picklist field> = 10   then return 43 as value

IF <Value from Picklist field> = 17   then return 46 as value

I then need to be able to use the returned value in another formula field which can have a further expression to resolve

IF<Value from Picklist field> = Yes then multiply the value from above result by 2

Your thoughts on this much appreciated.

Regards

Steve
