setting a line to the stderror lower line

[cbart_1]

i know that this will set sMA to a SMA.
sMA.Set(SMA(iSMAPeriod)[0]);

but what i need to know is how to set it the lower line of the stderror indicator.

Hello cbart_1,

If lowerline is a plot you can access this without having to do anything additional to stderror indicator.

If it's not a plot, you can access it following principles of this sample:
Exposing indicator values that are not plots

im making an indicator but i need the just the one line for the indicator im making. Really i have another indicator that is similar to the stderror that has multiple lines but i just need one of them to plot in the indicator im making.

If you're looking for help with syntax, it may help to use the strategy wizard condition builder to construct in point and click interface. You can then view the code.

An example of setting a value of a multi-plot indicator:
Value.Set(Bollinger(2, 14).Upper[0]);
