Can I set a limit on Inventory or Gift registry widget based on calculation?

I am creating a form for camp program registration.

there is a limit of 70 total registrants.

but a limit of 50 seats on a bus. With the option to drive.

Using 2 inventory widgets, one for signing up for the bus and one for signing up to drive 

or

Using the gift registry widget, selecting one of 2 transportation methods - bus or driving.

Can I make the driving option limitation on either widget a calculation of 70 - {bus spots left}?

that way I can ensure we do not go over the total of 70.

Thank you

Hello 😊 I get what you mean and what you're trying to accomplish but I'm afraid there's no way to setup the limits of widgets based on a calculation. The limits are set (and can only set) manually within the Widget's Wizard.

As an alternative, why not approach it in this way https://form.jotform.com/70825276838972

On the sample form I created above, I crafted my questions in a way that people who will attend will fill out the 70 slots regardless of how they want to reach the camp.

Once they fill out the Inventory Widget, they will be presented with a question whether they will ride the bus or drive. If they select "Bus", only then will they be able to fill out the 50 slots for the bus seats.

Thank you,

I have taken your suggestion
