Problem with Jquery Form

[fahelo]

Hi Guys,
I need some help in the following problem, that I have when I trying to record a Script using QTP 11 with the Web Add-in:

I need to enter data into a JQUERY form, at the following site <<removed link>>



The problem is that for example in the field "Ciudad de Destino" is disabled if I didn´t set the value in "Ciudad de Origen" first, but even the Script set first the value in "Ciudad de Origen", when you submit that second value, the site does not recognize that the first field is filled.

I tried to assign the value to the object but the site still does not recognize the values​​.

I´d appreciate if someone that maybe had the same issue can help me with an idea to solve this. I attach the Script that I´m using for do this.

Thanks!
