How to copy a vlaue from one forms into another forms value

[Kev]

Hello 

I have a Forms in confluence, which is triggering a JIRA-Item(EPIC). In JIRA we use the Summary and the EPIC-Name as equal. That means in the confluence form i have to fill out: EPIC-Name and EPIC-Summary. So i would like, that my stakeholders only needs to define the Summary and don't have to copy paste the summary into the name field. 

Therefore i'm looking for a solution to make a hidden-form for the EPIC-Name and it gets the value from the EPIC-Summary. so that the stakeholder which is using my form in confluence don't have to copy paste the Summary to the Name field --> to get rid of the Name field and it will be done automatically. 

But how to copy the input from one field into the hidden field? 
Anyone? :-) Thx a lot

Hi @Kev welcome to the community.  You must also have scriptrunner to perform this action correct?  If the answer is yes then simply modify the scriptrunner script that is performing the action in the background to pull the value from EPIC-Summary into Name field.
