I had posted a message a few days back regarding a perl script which was not able to click a button on a web form I'm trying to fill and navigate to the subsequent page.
I presumed the error was due to the button value which had the &NBSP character. Apparently, I had tried a couple of other pages and am encountering the same error so I guess its something to do with the click_button() or the javaScript embedded in the HTML. The queries I have are:

a) Does form filling using www::Mechanize, more specifically the click_button function work if the form's such that on clicking, it goes to a javaScript??

b) I've heard many times that Mechanize can't handle JavaScript() but is there a solution to move to the next page for this particular source code: (It's a bit long, so I've pasted the essential part of it)

I kinda have to navigate to the next page using my script at the earliest, kindly reply as soon as possible. Thanks a ton.
