Date picker

[it9888]

Hi everyone,I'm using some script that i found on the internet. It's a Date picker, really good, but i need one small addition to it. I'm not familiar with javascript, so i cannot do it myself. Basically, what i have here is a booking engine. The user selects the "starting date"and what i want is that the "ending date" automatically changes to a week later from the starting date. Here's the code:
