How can I change the available numbers for each tours in the Gift Registry widget?

Initially I had each of the tours set up to allow only 50 folks to sign up for each one.  I know have a situation where one person wants to change from tour 2 to tour 1.  How do I change the current numbers listed (tour 1: 40, tour 2: 9 & tour 3: 36 remaining) to reflect what I actually want?

Thank you.-Jeff

You have to edit the widget and add or subtract the numbers from its current value. For example, if you want to add 10 in the Tour 1, just put 60 in the bracket. If you want to subtract 10, put 40 there.
