MC,
You DAH MAN! Thanks!
Tried the code and it works fine.
Ed, one other problem that I noticed was your date calls. If per
chance you plot on a nontrading day you won't get an output. The
other day I posted a code that resolves the problem by using alert
and one you might want to consider as part of your code as well. Its
below.
Preston
D1:=Input("Day",1,31,30);
M1:=Input("Month",1,12,12);
Y1:= Input("Year",1900,2400,2000);
D:=DayOfMonth(); M:=Month(); Y:=Year();
Date:=D>=D1 AND M=M1 AND Y=Y1 OR Y>Y1 OR Y=Y1 AND M>M1;
Start:=Date AND Alert(Date=0,2);
ValStart:=ValueWhen(1,Start,C);
Valstart;
