Trouble with LoadVars.send

I’m having a little trouble with basic LoadVars.send in MX.

I’m just sending a variable to a database.

If I open a new window:

saveLoadVars.send(“update.cfm”,"_blank",“post”)

everything works fine but I’d prefer not to open a window, I’d prefer to send my variables to a page that doesn’t appear onscreen and allow my flash app to just keep running).

But if I just send the variables without specifying anything else:

saveLoadVars.send(“update.cfm”)

It doesn’t write to the database (I have a second window open where I can monitor this).

I know this is a really basic thing to do, and I can’t figure out what I’m doing wrong.

Any help would be appreciated.
