change the link in actions

[maas]

Hello All,

I am having a label which it has in its action a hyperlink.

The code which I am using:

on (release)
{
get URL("Main/active.pdf","_blank")
}
and it will display the file while clicking on the label.

Now, Instead I want the label to open the "Main" Folder directory. I tried to remove the file name, but i did not success.

So, how to do that.

Thanks in advance for your help
