How to create a validator for checking whether attachment exists?

[Sharaj]

I want to add couple validators before moving to the next transition. 1)Whether attachment exists? 2) Whether a particular text such as "client" is present in description.

I tried field required validator for attachment but it doesn't work.

Can someone please help?

Do I need to install this plugin separately?

It could be done with script validator provided by ScriptRunner plugin. Are you able to use it?
