Bootstrap Conitional

[Mergon]

I am currently trying to create a Class Ability.

This ability has a Custom expression that permits a selection of a necrotic cantrip from any class.

I have added all (2) necrotic cantrips to the Ability's bootstraps.

What I need is a condition for these bootstraps that checks to see if the selected cantrip matches the bootstrapped cantrip.

i.e.: The spChilTouc (Chill Touch) bootstrap needs to check and see if selected from the Custom Expression menu.

I've tried several ideas but Bootstrap conditionals are still giving me issues figuring out.
