What do you mean properties?

if (BarCntr>4){
for (i=1;i<4;++i){
vpast = ref(-i);
if (vpast[3]==null){
return;
}
!!! mR = vpast[3];
Sum+=mR;
debugPrintln("i: " + i +" mR= " + mR);
}
This code is near the bottom of my function.It computes 3 other things and is trying to refer to previous values of the fourth thing it computes to find a 4 bar average(a fifth thing).And it says vpast has no properties.I previously defined var vpast=new Array(5); .

Hello Roderick,

When you set vpast = ref(-i) and you get the no properties error, it's telling you that bar -i didn't have any values returned to the chart on that bar. Try adding a null check for vpast before checking for vpast[3] == null and see if that helps. Checking for vpast[3] == null assumes that vpast was returned as a valid array.

    if (BarCntr>4){ 
        for (i=1;i<4;++i){
            vpast = ref(-i);
            if (vpast == null) return;
            if (vpast[3]==null) return;
            mR = vpast[3];
            Sum+=mR;
            debugPrintln("i: " + i +" mR= " + mR);
        }
    }
