Trouble passing information from one page to next in eCart

Tried to get a product number from WADAProd recordset to show up on eCart RequestforQuote.php page. First tried using eCarts predefined ID column. This column only returned a Session ID, or the Primrary ID from Db; not the Product Number.

Tried to create a new column called ProdNum, but received several errors - maybe because it was named the same as a column in another recordset.

Renamed as PrdNmber, but now receiving several new errors in both Prod_Results.php and eCart Object file (see PM).

Opened eCart 'get from recordset' file in Prod_Results.php (the page that submits to RequestforQuote.php), thinking maybe the error was in an eCart value there. Changed the value to one similar to other values that were working, but now getting this error, so unable to go any further:

Error in button onClick:

TypeError:
document.generalWP.document.recordset.options[document.generalWP.documnet.recordset.selectedIndex] has not properties.

The errors are viewable live only, as the 'headers already sent' error prevents local viewing.
