New record based on retrieved record problem !!

New record based on retrieved record problem !!

Hello 

Can someone point me in the right direction 

form 1 = Work template 
from 2 = Multi work steps associated with 1 work template 
from 3 = Project initiation by selecting a work template

in form 3
I want to be able to create new work steps (from 2) associated with  the new projet

I managed to create the new records in form 2 but I can't seem to find the way tranfert the information from the inital steps to the new steps 

See attach image 


Thank you 

Pierre
