Can we add values into a custom field using script runner in jira

Question

I have 2 fields named X AND Y.

X is a test filed

Y is a drop down field having values like India, Srilanka etc.

Requirement -

Customer will give some value in X field, system will check whether that field is present in Y or not, if not need to add that value in Y field.

Is it feasible we are using JIRA server version.
