Well the fault/error in the javascript needs to be corrected - if you are the author of the page then you need to debug your javascript.

As for using the page there is no harm in using it - but it probably will not do what its supposed to do as the javascript within the page is not working.
This means that some of the Javascript code within the web page that has just been downloaded contains syntax or logic errors. As a consequence certain parts of the web page may not work as the author intended.
