This is a small change that I need made to the last application you worked on for me. I have both calculators on one page. There is a selection option that first comes up and when you select your measurement system then it hides the selection option. My problem is that when you submit the form to calculate when the page refreshes the selection option shows up again instead of just the calculator you chose with the results for that calculator. Can you fix this I imagine it will be extremely simple for you.
