I`ve tried several times to buy the 1900D but each time after completing my details, I get an error asking me to enter a value into the "Bill to: zip" at the top LHSide. I`m not sure what I am supposed to enter but when I try I am unable to write anything in this field.Please can someone help and elderly idiot solve the mystery?Many thankGeorge Aldridge

Hi George,It appears as if you are either omitting your zip code, or entering your zip code incorrectly.Let us know if you continue to have problems.Best,Vin ScimonePMDGwww.precisionmanuals.comhttp://www.precisionmanuals.com/images/forum/devteam.jpg
