JS menu include (help)

I like to include to js files (dropdown nav menu) however when I place it say under the VB menu buttons===>>

<SCRIPT language=JavaScript src="menu_array.js" type=text/javascript></SCRIPT>
<SCRIPT language=JavaScript src="mmenu.js" type=text/javascript></SCRIPT>

I get script errors

the system is from dynamicdrive.com
I have included the original zipped file from them if you would like to look at it, I have edited the one that I have, and it works fine outsite of VB, I want to know if there is another way to include them....

can anyone help me
