Ultimately what i want is to be able to pull a URL (that points to a
sharepoint list) from my form, and get the max ID that currently exists
in that sharepoint list.

I think i need to use one of the web services built into sharepoint,
but i have not seen any jscript example on how to do this.  Is this
even possible?  Any help that could be provided here would be greatly
appreciated.

Thanks,
T-Bone
