Hi Schotja
I am fairly new to FM7 myself but i have done what you want to do.
"When a new record is created in CmplxFile1, i want a new record created in simplefile2, automatically with the exact data from the two fields populating the records in simplefile2."
in the relationship box, choose CmplxFile1 on the left side and Simplefile2 on the right side and check the box on the right side that states "Create New record in related file."
Write a script and use the set field command to populate the two fields that you want.
I hope this helps and i think i got the relationships right, if not, just reverse them.
