Hi,

I'm a ruby newbie, although I'm a programmer with 10yrs experience.  I 
was running myself through the tutorial in Agile Web Development With 
Rails, when I ran into a problem.  somewhere in the code I mistakenly 
entered

@items = 0

instead of

@items = []

A bit later I tried the following

@items << LineItem.for_product(product)

but when i try to execute this code I got the following error:

"cannot convert LineItem to Integer"

Looking back through the code, I found the error mentioned above, and 
corrected it.  However, Rails still insists that @items is an Integer. 
Can anyone suggest what has gone wrong, or what I can do to fix it?

Alli
