After you extract the table into listpickdata, use the advanced list block Make A New List From Other List to feed the Elements directly, no loop needed and no temporary list needed.

P.S. Don't excrete where you eat
Nor extrude, it's rude
Your plate is not a toilet
I have setup an example aia project, spreadsheet and form for you to look at and hopefully use as a template. The spreadsheet has two worksheets, one for the product listing, the other for the form submissions. You need to keep these as plain columns and rows, no sub headings, merged columns.
The google form is linked to the second worksheet: MntceResponses, form submissions will be placed and shown here. The spreadsheet is set to "Anyone with the link can view". I left out the barcode images, might be better to provide a url for these.
The aia project has three functions:
GetProductData
This will return all the data in the first worksheet: Products.
SubmitMntceData
This will submit data from the five textboxes to the google form, then on to the second worksheet:MntceResponses
GetMntceData
This will return all the data from the worksheet:MntceResponses
I have used three web components to keep things simple (you could use just one if you used action variables)
