I need help scripting color Zero Line above/below candle

[jack1]

Hi- I tried zeroline.assignvaluecolor etc and even assign assignpricecolor etc. for this zeroline script below, and all I get is a green line whether the candle is above or below the zeroline (which should be green or red depending on the location of candle close. Also is there a way to code the zeroline to not require checking the left axis box. Thanks for any help. :

TOS stock script requires checking the left axis box :

plot Zero = 0;
Zero.setPaintingStrategy(paintingStrategy.LINE);
zero.setdefaultColor(color.light_gray);

My attempt :
zeroline.assignvaluecolor( if close > zeroline then color.green else color.red);

assignPriceColor( if close > zeroline then color.green else color.red);

I don't know how to code to use the right axis instead of requiring checking left axis box

Thanks,

@jack1 We can't be of much help if we don't know the code for the entire indicator... Is this an Upper or Lower indicator...??? Your AssignValueColor() and AssignPriceColor() logic appears correct but what is it based against...??? If you base close off of Zero then the line will always be Green because no Symbol ever trades below Zero... We need more detail into what, exactly, you are attempting to do...
