My granddaughters orchid was left in a cold house and the blooms dropped off. It was potted properly by a florist. There are just the sticks left on the plant. I just put the plant in a south facing window and it feels damp enough. Help!

Just be sure that the orchid does not get direct light all day. This will worsen your issue. These are very cold sensitive. Now, unfortunately... There is a list of requirements that must be met in order to get this to bloom again. Orchids are photoperiodic. This means that they will not flower until the hours of pitch black darkness exceeds the amount of daylight that it receives. You must first give it about 18 hours of bright, but indirect, light per day for a couple of months so that it can recover. Do not cut the flowering stalks as they can rebloom from these. Now after the couple of months of long day length, you will want to make sure it get less than 12 hours of light per day, and more than 12 hours of pitch black per day. This simulates a "winter" without the cold. After you meet these requirement, and a few more, then it will flower again.
Here is an article that explains everything but the Change of the light cycle. I have given you that explanation above: https://www.gardeningknowhow.com/ornamental/flowers/orchids/make-orchid-bloom.htm
