Need help with Linear Regression Reversal Watchlist Column Code

Hello. I keep getting errors on this code. Please suggest an answer!

The goal for this watchlist column is to change background color when Linear Reg Reversal is equal to 1 AND when CCI (5) Crosses Zero. Agg period is 2 days.

Code:
def agg = AggregationPeriod.TWO_DAYS;
def lrr = reference LinearRegrReversal()."LRR"(period = agg);
def cci = reference CCI("length" = 5)."CCI"(period = agg);
def zeroLine = reference CCI("length" = 5)."ZeroLine"(period = agg);

plot scan = if lrr == 1 and cci crosses above zeroLine then 1 else if lrr == 1 and cci crosses below zeroLine then -1 else 0;
scan.AssignBackgroundColor(if scan == 1 then Color.WHITE else if scan == -1 then Color.RED else Color.GRAY);

there are several things wrong here...

can't use 2nd agg in a scan or watch list

can't apply 2nd agg to a function. has to be used with a price constant,
open, high, low, close

can't append input parameters with a 2nd set of ( ) at end of a function. all valid input parameters need to be within the main set of ( ).

AssignBackgroundColor() is its own function. it is not used as a plotting parameter.

no need to read 0 from another study.
zeroline= ???
just use 0



looks like you want all your variables to have data from '2 days' time,...
so just set the column time to be 2 days, and don't try to read 2nd agg data in the study.

Thanks so much for your reply. The code works as expected since you corrected all those errors. Much appreciated!
