Two JavaScripts conflicting, but why?

[OMD]

I am trying to use two scripts on one page one is a DHTML menu the other a site search. I cannot find the conflicting variable. I get this error
'Item[...]' is null or not an object
The script is attached, please help if you can, thank you.

you declared item as one-dimensional array but you use it as two-dimensional array:

item[i][order[j]]

[OMD]

Thanks glenngv!

I see disparancies between your script eample and the one I am trying to run, as to how to correct it, no. I am in over my head in that regard. I have little experiance with JavaScript beyond inserting scripts into my HTML code. I can on occassion modify or fix scripts but this one is elluding me.
Thanks!
