Way to re-evaluate once parameters have been parsed

[thenom]

Simple example of issue:

I am basically trying to find a way of using the value from a parameter as the name of another parameter to get its value.

Any ideas?

Was thinking about a custom function but started getting a bit messy in my head. Kind of just checking that there isnt a way to do this natively?

Thanks in advance
