im' trying to use FreeMaster to read a varible on my M523xEVB!
Freemaster run well and i can see the value of my variable on the WatchGrid.
So i write this Javascript to see it in the html command window:

<object name="pcm" width="0" height="0"classid="clsid:48A185F1-FFDB-11D3-80E3-00C04F176153"></object><script language="JavaScript">    var val,val2,error,a;  succ = pcm.ReadVariable("encoder_ssi",val,val2,error);  if(succ)  {   document.write(succ);    document.write(val);  }  else  {    document.write(succ);    document.write(error);  } </script>

 This code on the html control page return

succ = "true"
val    = "undefined"

Why can't i see the value of val if succ is true and i can read the variable on the watch-grid?

thanks at all! :smileywink:
