I thought I'd built two simple, working HTML calculators (I have only a little bit of experience).
But they are both in conflict with one another. When I remove the 2nd, the 1st one works. So they seem to be in conflict but I have no idea what to do. I've attached a picture of what the two code injections looks like.
And here's the link to the page with the two calculators.
Any help would be much appreciated.
