If Statements to alter select field options Jira Behaviours

[bSte]

I am trying to get the script below to work - I have tried adding it to each field in behaviours as well as on one field. The issue appears once I add the additional if statement. I have also tried this with an && statement which also breaks.

Basically - I am trying to get a field to show select options based on the values selected in the 3 fields above. I can get it to work for one field but once I add the second field via if statement or && breaks the code and nothing works. 

Thanks so much for your help!
