Sorry about that.
I have a form page that lets a customer custom configure a computer system
and then add it to the shopping cart. Upon the adding of the first computer
to the cart the form variables pass over just fine and everything is hunky
dory, and if they add another system, that is fine also. The problem comes
in when the user decides to update the quantity of units purchased. When
they hit the update button, which their is just one on the page 2 things can
happen depending if their is hidden fields on the page or not.
1 If there is hidden fields, I can update 1 system just fine and pass all
the variables to the structure. If I try 2 systems then I have a comma
delimeted list of variables that passes and that wont work
2. If there is not any hidden fields, I get an error that it cannot find a
variable that it is looking for.
This is view cart page that posts back to itself
