Hidden placeholder?

[numberz]

I'm trying to figure this out.

If I have a production rate, along with a production rate percentage,

And if I change the production rate and the production rate percentage changes to suit the percentage of the production rate new number...

How can I change the production rate back to original, when I change the production rate percentage back to 100%

In another program we had a hidden field called original production rate that took care of this issue.

Solved: I had to create another Attribute call OriginalProdrate
