Javascripts won't work with each other

Javascripts won't work with each other

Hello!,

 

My name is Rokain and I'm working on my own site located here.
As you can see I use a contact form where people can contact me.
In the contact form you can check a checkbox, if you check this checkbox some other inputs will roll out.
This all works when I use the latest jquery and also the javascript files form my contact form, except for the "formcheck.js".


 

Formcheck.js checks if every required field has been filled in, if not, it will give an error.
As long as I keep jquery.js out of my code, formcheck.js will work but then are the hidden divs (behind the checkbox) already visible.
When I put the jquery.js in my script, the divs behind the checkbox are hidden, but formcheck.js won't do its job anymore, so it won't check all the fields if they have been filled in.

 

Is there something I can do about this?
I use the latest jquery and the formcheck.js file is located below.

 

Thanks in advance.

 

Kind regards,
Rokain
