[ScriptRunner] Update a sub-task(s) "version picker" field if parent ticket field value updated

[Daniel Rocha]

Hi,

I discovered this question that's very similar to my desire, but I couldn't alter the script to serve to my porpose. I'm new to groovy and I am having problems to adapt the script. My problem is to update a "Multiple version picker" field.

Can someone help me, please?

Thanks in advance.
