How do I use an Applescript string in Javascript?

Question

I'm trying to get the contents of a BBEdit window, push them to a textarea on a web page, then click a button.
Here's the applescript that does it:
set scrpt to "Testing"
(* tell application "BBEdit"
set scrpt to contents of text window 1
end tell*)
if scrpt is not "" then
tell application "Safari"
set index of window "Question Editor" to 1
tell document "Question Editor"
do JavaScript "document.getElementsByName('question')[0].value =scrpt"
end tell
tell document 1
do JavaScript "<clicks the button>"
end tell
end tell
end if
You'll see some of my elementary debugging at the top. scrpt is a variable that contains the text from BBEdit. You'll see scrpt at the end of the first do javascript() call. If I literally put a string inside the do javascript() call -- removing scrpt altogether -- all is well.
But no mater how I assign a value to scrpt, either directly or via bbedit, the javascript fails. Any ideas? I wonder if scrpt has something extra around it, like quotes, or if somehow it's not passed as a string.

Well, the obvious problem is:
do JavaScript "document.getElementsByName('question')[0].value =scrpt"
You're including the literal string 'scrpt' in your JavaScript command, so those 5 characters are exactly what's sent to JavaScript to execute.
A better aproach would be:
do JavaScript "document.getElementsByName('question')[0].value='" & scrpt & "'"
note that your scrpt variable is no longer quoted, so AppleScript will embed the variable's value into the command. I've also wrapped scrpt with single quotes to protect the value, in case it has spaces or some such.
