Correct! I was asserting that you had tested this:

print "Content-type: text/html\n\n";
$myDocument;
[download]

but posted this:

print "Content-type: text/html\n\n",
$myDocument;
[download]

A comma would mean that $myDocument is the second argument to the print statement, and should work. A semi-colon would mean that $myDocument was a statement in itself, which is nonsensical, and will give you the error message you posted.

I think that you actually tested using a semi-colon twice, and happened to mis-key the semi-colon when you posted the first time, changing it into a comma and fixing your own problem! (Or maybe larsen fixed your error, and you cut-and-pasted his correction ?)

Can you test your program again, making sure you have only a comma between "Content-type: text/html\n\n" and $myDocument ?
