RSI quits plotting intermittently

[HJSeese]

In my study, I calculate the difference between an RSI(2) and a calculated RSI. For some bars, the RSI(2) is not plotted. I have overlayed a RSI to verify this.

This picture shows the problem.

How does one fix this? Should I call the RSI a different way? I have tried also calling it as a series object and as retrieving single values.

I have found the following section of code that if taken out allows the RSI2 to plot correctly.

var vtemp=0;
var vtemp_1=0;
var vtemp2=0;
var vtemp2_1=0;

// this section cause rsi to boobooooooooooooooooooooooooooooooooooooooo
for (i=fromIndex; i < barC+1; i++)
{
    nn =i-barC;
   var vchg = close(nn)-close(nn-1);
    vtemp_1 = vtemp;
    vtemp2_1 = vtemp2;
   if (isNaN( vchg ) == true) { vchg = 0; }
    vtemp = scaleVal*vchg + (1-scaleVal)*vtemp_1;

    var vabsChg = Math.abs(vchg);
    vtemp2= scaleVal*vabsChg + (1-scaleVal)*vtemp2_1;
 }
//////////////////////////////////////to here
vnetChgAvg= vtemp;
vtotChgAvg = vtemp2;
 

if ((vnetChgAvg)!=0 && (vtotChgAvg)!=0)
{
    rsiPO= 50*(vnetChgAvg/ vtotChgAvg+1);
}
else { rsiPO= rsiPO_1; }


if (bExpired)
{
    rsiPO=50;
}

vbss  = Math.abs(rsi(2,0)-rsiPO);

return  Array(rsiPO, rsi(2),vbss);

}

Just a very quick look revealed that the return statement needs correction:
replace it with:

return  new Array(rsiPO, rsi(2),vbss);

No difference with that change.
