Looking for complete zencart fileset of a Request for Quote form, preferably one with jquery/javascript code for user to add/delete rows for multiple (eg length, width, qty) input fields per row.

The specific parts I need are:
jquery/javascript code for user to add/delete rows
code to push the added row inputs into an array
code to calculate the product of each row of inputs
code to calculate the sum of the products of each row of inputs and insertion into single db field
code to insert whole array into a single db field
code to extract the inputs from the array to display in an email.


Happy to turn this into a mod for the benefit of others.
