How do I limit quantities of inventory widget

You must be referring to the Inventory widget on your form.

To limit the inventory quantity, you should set a number in the Available Quantity option of the widget settings. I noticed that you have left it empty on the widget on your form.

To fix it, put the quantity you want to limit the available inventory you have.

Let us know if you need further assistance.

I have checked your form, http://www.jotform.us/form/71243276249155 and I see that you have set a price for each registration (submission).

Also, if I'm understanding your requirements correctly, you are only expecting to have 16 registration for the said form. Then, you only want to use the Inventory Widget to show the remaining entries available. And aside from that, you don't want to your registrants to be able to select multiple or more than one items in the Inventory widget.

If that is the case, then I would suggest you use the Submission Counter widget instead of the Inventory widget. Then, set a submission limit on your form base on the number of submissions allowed. How-to-Limit-Submissions-in-a-Form

The widget, as shown in the image above also allows you to customize the text before and after the remaining value.

Below is what I understand, so far, on what you're trying to accomplish with your form.

1. You would like to have a field in your form (possibly a drop-down field) to list the range that is allowed to register.

2. You would like to limit one selection per option in the said (drop-down) field. This means that once an option is previously selected, it can no longer be selected again by other registrants.

3. You would like to show an inventory of the selected age range on your form.

I would like to apologize, however, we may need to ask for more information regarding your recent requirements.

We will wait for your response.

Thank you.
