My Easy Language needs help!

[JOHN CLEMENk <jbclem@xxxxxxxxxxxxxx>]

This is a simple indicator I'm creating:

Input:  Input1(close of data1), input2(close of data2), xaverage(19);

Plot1(Cum(input1-input2), "CumUPDN Vol");
Plot2(xaverage(Cum(input1-input2),19), "CumUPDN Vol");

When I try to verify it I keep getting the error message that a comma is
required on the Plot2 line between the open parenthesis and the C of Cum. 
I've changed the line around as much as I can and still get the error
message.  Can someone suggest a solution.

Thanks,  John
