Ive been getting this error message everytime someone visits my site...

File does not exist: /home/urtascom/public_html/404.shtml, referer: http://www.urtaggs.com/
File does not exist: /home/urtascom/public_html/js/myjavascriptajax.js, referer: http://www.urtaggs.com/

it says that myjavascriptajax.js doesnt exist, and it doesnt.

i do have myjavascriptadmin.js

Do i need to create this file, or is it referenced wrong somewhere in my script?

-Thanks for the help
