I am trying to use parameter settings to group EW internal and
external retracements. I have written the function in the code below
in an attempt to return the value only if it meets the "group"
requirement of the function. I have tried weveral ways and have not
been able to use the parameter settings to separate the retracement
levels by group, could someone please help me.
TIA

Plot( Close, "Close", 20, 64);
//Progressive EW//
RE=Study("RE",GetChartID());Plot(re,"Pr Pivot",15,8);
SU=Study("SU",GetChartID());Plot(su,"Pr Pivot",8,8);
x=re-su;
//*Retracements*//
function IER(factor,group)
{
ir=x*(factor)+su;
retval=ValueWhen(group,ir,1);//return value by group
ret=retval;
return ret;
}
I1=Param("38,50",1,1,9,1);
I2=Param("162,200",2,1,9,1);
ir38=ier(0.382,I1);Plot(ir38,"38% Ret",colorRed);
ir50=ier(0.50,I1);Plot(ir50,"50% Ret",colorRed);
er162=ier(1.618,I2);Plot(er162,"162% Ret",colorRed);
er200=ier(2.0,I2);Plot(er200,"200% Ret",colorRed);
