Maybe we should have a max of 99 so that it doesn't crash if you put in a number
too large to handle

Or handle it in the JS code

I think this is a merge error. David recently deleted
this section, and when you rebased you added it back.

[ultimatedbz, 2016/10/28 23:51:43]

Oh! My bad. I will be more careful the next time I rebase and merge.
