The custom javascript option has been deprecated. Please note that if you have used custom javascript in your existing forms or create new forms by making a copy of the existing forms in Neartail, the custom javascript will continue to work without issues. Instead of using a custom script for managing inventory, I'd recommend you to use the Neartail templates to create your order form and enable the inventory option to set up available stock for your products. Neartail will keep track of product orders and automatically mark the product as sold out when the available stock becomes zero.

Configure order summary Configure option to update the summary settings page will be displayed only if you have added the ${BILL()} or ${response()} formula to show an order summary.  In the Neartail Edit page, click on the gear icon next to the "Review and place your order" title > Header settings page will be displayed > enter the ${BILL()} formula in the description option and click Save. Note: You can also access the summary settings page directly. In the Neartail Edit page, click on the gear icon next to the form title > Form settings page will be displayed > click on the Configure key fields icon next to the Save button in the bottom right corner > Summary settings page will be displayed > you can map the relevant fields for order summary. Format prices to convert questions in Google Forms to products When you enable the format prices option to calculate the order amount using the Neartail addon, Neartail automatically converts the questions with price into products. If the unit measure is not set correctly in your form, you can manually update it. Change unit to measure from weight to quantity In the Neartail Edit page, click on the gear icon next to the product > Product settings page will be displayed > click Advanced > click Change for the Unit of measure option > select Quantity and click Save. Once you change the unit of measure, you can also update the default quantity options and the price as well.  If you are facing any issues with updating the unit of measure, please let us know.

Update: We have fixed the issue with the addon.
