I can't give you precise measurements because I don't know exactly how much you have. It sounds like not enough glycerin, too much powdered sugar, and possibly climate problems. Be sure to knead until your arms are putty. Fondant is a workout and an experiment.
Check your corn syrup. If its thinner than honey, make a new batch, use more gelatin, and remember to let the heated mixture cool. It's almost impossible to repair fondant when the syrup mixture is too hot. This adds almost two extra cups of sugar to make it look right - until the next day.
If nothing else, freeze what you have and mix with new fondant as needed for decorations.
