Did this question ever get a resolution.
I checked the web and removed all the chr 13 and nulls from my data, and I still get the same error as this guy did 3 years ago.

Folks,
I have reached page 187 of the book with the code to create the detail.asp
page. When testing the page I get the error
EstoreCommerce error '800a005e'
Invalid use of Null
/NoNameWebStore_Local/en/detail.asp, line 44
Line 44 of the page corresponds to:
mfrname = Product.MfrName
I have double checked the code in both detail.asp and the Product class
module of the WroxCommerce component but couldn't find any spelling
mistake.
I am quite a beginner with ASP and I don't exactly know what causes this
error. Does anyone have a suggestion on what may be the cause and how I
can resolve this problem? Thank you.

Null is a somewhat tricky subject b/c it is technically not "0" nor is it
"nothing" but rather it is "unknown" (for example, if you have two database
fields that are "null" and you compare one to the other, such as "if
field1=field2 then..." and both were null, this would result in "false"
because null is not equal to null since both are unknown values. Chances
are somewhere in your code you are referencing a null value incorrectly.
