I want to set the value of urgency custom field based on the value of priority and impact custom fields

Question

Hi,
I have a request to automatically set the urgency custom field value based on the value of other two custom fields (priority and impact). We have script runner installed but don't know what is the best way to do that.
Note: we want to set this while creating the issue,but not as a post function.
Thanks

That's one of the (many) reasons not to try it in javascript and do it the reliable way, in a post-function.  For javascript, you're going to need to intercept new page and refresh and update page and other javascript events that update the page.

Thank you very much for your reply.
I already created the java script and I put it in the field description but the problem that if I changed the project or the issue type and changed it back to the issue that has this script in one of its filed, Jira does not load the script again, it just ignore it.

Ah, I see, you want to fill a field with a default value based on other values, allow the user to overwrite it, and have their data over-written if they go back and amend the other values.

Definitely possible, but best done in javascript, which isn't my field.
