Why doesn't LoadVars() work?

I have a txt file in the folder “info” containing:
&load=10

In the fla file i have this code in the first frame:

folder = “info/”;

infoVars = new LoadVars();
infoVars.load(folder+“info.txt”);

trace(infoVars.load);


When i run my movie, infoVars.load returns
undefined instead of 10.

Can someone help me???
