jslint.com gives the line where the errors occur, but im not sure how to fix

Appreciate all help.

Rather than having us debug all of that code, which line does it say is the problem? (Maybe post the three-four surrounding lines as well, in case the error is from those.)

I get this error:

[Server_Error] missing ; before statement while calling uploadprogressmeterstatus.get_status()

[newbtophp]

Anyone can help? :9

I don't think this is necessarily an error in the code above. That says there was an error while calling the function.
First you define a function in the script section at the top of the page then later you call it to use the function-- either in the body of the page or somewhere later in the script section at the top. But since I don't see anything here, I am guessing that you are missing a semicolon when you call the script.
For example:
<element onClick=uploadprogressmeterstatus.get_status();">

Though Javascript allows missing semicolons (unlike many other languages), it can make things much harder to debug and also confusing to read-- I'm guessing that IE is just wanting you to be completely correct, rather than relying on a questionable method of calling a function (skipping the semicolon). In general from what I've seen this won't hurt anything, but it looks like IE is going to give a warning. Did this mean that the script didn't function, or there was just a warning even though it did work?
