I am trying to use datepicker inside a messi dialog box ( http://marcosesperon.es/apps/messi/) which also uses jquery. 

Basically, a button is clicked, the dialog box pops up and in the dialog box is a form. The form contains a date field, which I want to attach datepicker to. 

However, when I click in the input box, nothing happens. 

I know the datepicker is working because if I put the input box on the php page and not in the dialog box, it appears fine. 

Can anyone help?
