Hello guys,
I'm not a developper and have very little knowledge in programming. I'm trying to modify the following line.

I need to grab only the first or last 4 characters of the "Package.ID" after the "720" what's the correct way of doing it?

the_id = "ABCD${asset?.PlatformAsset?.Package.ID}720${asset?.PlatformAsset?.Package.ID}3"

Thank you

Where are you doing this and in which Atlassian application?

This gives you first four character,

${asset?.PlatformAsset?.Package.ID.substring(4)}

and, this gives you last three,

${asset?.PlatformAsset?.Package.ID.take(3).reverse()}

Thanks.

I tried but it's not working, for some reason.
