Either a non-numeric or a value outside that range.

The data is pass in numeric 1,2,3 and i want to view it as Jan, Feb, Mar

You formula works for my test when I created a parameter and passed 1,2,3 in.

Are you sure the value is entered as shown.  I tried 1,2,34 and got your error

I tried 1,2,3 4 and got a non-numeric string error.

WHy not use a numeric parameter and pass in multiple values. They will already be in an array.
