How do I chose nseason & xlag values in proc varmax?

Hi,

I'm trying to forecast sales on the weekly level for 12 weeks suing SAS Enterprise Guide 7.1.

I have my code as follows:

proc varmax data = weeklevel plots=all;
id week_end interval = week;
model sales_net/ method = ml nseason =  xlag =;
output out=wint_add_out_weekly back=12 lead=12;
run;

I have my data at week level, with week beginning on wednesday & ending on Tuesday. Based on the following trend & seasonality, how do I enter the values for "nseason" & "xlag"?
