Creating a simple Business Rule to copy one field into another field

The solution is pretty easy, find SugarBPM below.

I just tested on Quotes and it worked like a charm.

Yes, I'm sure it's simple but I'm struggling with the rule set-up...  I have a Process identical to your image.

I started with the condition that the autoincrement field isn't "9999" but I'm not sure what the "return" should be...

I have other rules where I return drop-down values or insert text...  What does the "return side" look like in you

Thanks for being gentle with me - I don't have a lot of experience with Business Rules

Find Condition definition for trigger of SugarBPM process.

I'm not being very clear.  I have the Process written - Trigger / apply rule / End.  I'm having difficulty with the Rule that copies the number.  Here's a screenshot of one of my attempts.  I'm not understanding the "return" part.
