How to limit choices in Google Forms
When each option has its own capacity, the problem is not the whole form — it is the individual choice. FormGuard helps you manage quotas for slots, sessions, roles, and limited options.
The problem
Google Forms can collect multiple-choice, dropdown, and checkbox answers, but native Forms does not behave like a booking system. If each option has limited capacity, someone has to watch the spreadsheet unless you add a choice limiter workflow.
FormGuard is designed for Google Forms users who want practical controls without rebuilding the form in a heavier form builder.
How to do it with FormGuard
- Install FormGuard: Add FormGuard from the Google Workspace Marketplace.
- Choose the question to control: Use the option list that represents slots, sessions, roles, classes, or inventory.
- Set quota values: Give each choice a capacity based on how many people can select it.
- Add backup instructions: Tell users what to do if their preferred option is full.
- Run a test: Submit sample responses until a choice reaches its limit.

Limit each time slot so two many people do not pick the same time.
Workshop tracks
Cap each breakout session independently.
Volunteer roles
Avoid getting too many people for one role and none for another.
Class selection
Limit cohorts, sections, or class seats.
Limited inventory
Treat choices like simple inventory buckets.

Can FormGuard limit both choices and total responses?
Yes. You can use choice quotas and response limits together.
Is this the same as Choice Eliminator?
It is similar in intent for users who need choice limits, but FormGuard also focuses on response limits, notifications, and timer-style workflows.
