Ok, I have hit a stumbling block I can't seem to get around and would appreciate some help.
I am programming in javascript and html.
I pass a bunch of variables on the url:
called.html?a=1&b=2&c=3 ...etc...
when called.html gets loaded I need to take one of the variables off the url and display it in the middle of the page...
kind of like:
XXXXXXXXXXXXXXXXXx
XXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXX
a = <insert value here>
XXXXXXXXXXXx
XXXXXXXXXXXXXX
XXXXXXXXXXXX

So the way I get the variables off the url is by naming the html page is with the FORM tag. and then calling the page by name within the javascript.
but I can't figure out as the page is loading how to call the javascript to grab that variable from the url and then display it where I want to. The <body onload> isn't working cause I can't get it to work unless I have the javascript outside the first html tag, but if i do that, i don't know how to make it so the scripts can pull the data off the url if I don't use the form tag. I could use some help.
I know this is terrible programming and completely insecure, but it doesn't matter, it is the interface that matters not the guts of the backend...

Not sure what you mean by having the javascript outside the first html tag. Are you referring to the initial <html> tag? Have you tried placing it within the <head> block?

yes, doesn't work if I put it in the head block, the onload is called if I have the function located above the <html> tag, but then I can't get to the variables....
I am really trying to figure out if there is someway to make this work without having to call and onload function.

I see. The javascript in the first article crushing linked to works pretty well, and doesn't use an onLoad().
