hey vic,

Thanks for the code.

Im only stumbling on a small error as soon as I ad a second dropdown menu. They wont work together. If I set dropdown A to value 10 and then put dropdown B to 1 it shows the latest value change "B1=$95.00" instead of A10 + B1.

Any chance you know how to add this?

Thanks in advance,
I've changed it on my test site:
