Nine digit zip codes.

[James Hurley]

Richard,

I'm beginning to get it. I should put

>> visited
>> =1&pagenumber=0&firmname=&address2=620+moulton&address1=&city=los 
>> + 
>> angeles 
>> &state=ca&urbanization=&zip5=90031&submit.x=48&submit.y=8&submit=Fin



into field 1--or, of course, the data appropriate to my addresses.

But where did this "visited" line come from? Where in the process of  
sending the "submit" does this line present itself?

Jim
