extend lr average

["john Davis" <buglywugly@xxxxxxxxxxx>]

Can anyone tell me if it is possible to extend plot 2 forward like plot1 by 
using displace =-1.?? I have tried
writing it out like this but it tells me it needs more inputsl.
"Plot2[Displace]average(LinearRegValueFC(Price, Length1, 0), "LinearReg"); I 
know this is not the way you do it. can anyone tell me how to write it 
correctly, if it can be done?


Inputs: Price(Close),  Displace(-1),length1(25),LENGTH2(2) ;

If Displace > -1 OR CurrentBar > AbsValue(Displace) Then Begin
	Plot1[Displace](LinearRegValueFC(Price, Length1, 0), "LinearReg");
Plot2(Average(Plot1, Length2), "lrAvg" );

I want to extend plot 2 forward like plot 1.   thanks
