Hi,

I'm working on response from my Denon receiver. I'm having a little trouble filtering out the letters, e.g. I'm getting the response MV235 instead of the desired 235. I also have a panel tagged VOLUME on the page
I've made a page script that looks like this:
this first part is the actual page script.

var w, volume;
w = widget("VOLUME");
volume = 0;
w.label = volume;


this next part is actually a button script run once to make a query for the volume right away - I use the same script for volume up/down on the hard buttons, with an extra line; s.send("MVUP\r"); for adjusting the volume
var e,s;
e = CF.extender[0];
if (!e) {
Diagnostics.log("Extender 0 is not defined");
} else {
s = e.serial[0];
if (!s) {
Diagnostics.log("Extender 0 is not a serial extender");
} else {
s.bitrate = 9600;
s.databits = 8;
s.parity = 0; // None
s.stopbits = 1;
w.label = s.match("MV?\r","\r",250);
}
}

for filtering out the MV part of the response this should do it:
var volume = parseInt(response.match(/\d{2,3}/)[0]);

but where do I put that line of code to make work?
