hiding script temporarely

hiding script temporarely

I have contact form problem. The form fails to deliver a message. The source of the problem is  two conflicting script libraries. Both libraries are needed for different effects.

  1.     The fancy box scripts works with the image display mechanism.
        <script type="text/javascript" src="./fancybox/lib/jquery-1.10.1.min.js"></script>

        The jquery scripts works with contact form mechanism

If I remove the fancy box script the contact form works but lose the fancybox interactive image display features.

If I remove the ajax.googleapis script I loos the form functionality.

Changing the order of the scripts or loading them asynchronously has not worked.

Is there a way to hide the jquery fancybox script once the contact form is called.Then reinstate the fancybox script after the message has been submitted?
