I use two javascript libraries in the website : jquery and mootools.

 

There was indeed a conflict between the two and I used the noConflict() method.

 

And everything worked fine (almost) everywhere. It only causes problem in ie7.

 

I'm having this problem :

 

      Line : 3 
      Character : 41138 
      Problem : Object doesn't support this property or method

 

Here's the website (it's not finished and in french) : www.andreannegouin.com

 

Thanks for looking at my problem!
