How to make a download button?

Hi

I have a pdf-file. I need to make a button that starts to download the pdf.
At the moment my button code is this:


on(release)
{
getURL("/matskut/testi.pdf", "_blank");
}

So the pdf is on subfolder matskut and name of the pdf is testi.pdf

I get no error messages, but it won’t open/download the pdf.
I am running swf-file from my hard disc, could this be the problem?
or is my code bad?

thanks
