[Javascript] JavaScript syntax problem?

[javascript@xxxxxxxxxx (Dan)]

Hi all, 

The script below, embedded in html page, is causing me
some grief. While there is no syntax error message
generated, it does say the value passed in by
'filename' is undefined. So, if the value of filename
is "myfile.html", it complains about "myfile.html" not
being defined. 

My guess is that I made a mistake in the syntax of the
JavaScript below: 

document.write("<INPUT type='button' name='go_to'
value='Launch NOW' class='formButton' onclick
=launchNow(" + filename + ")>") 

Any ideas for correcting my error? 

Thanks.
