Payable Forms - User Specified Amounts
Response Validation in Google Forms
Response validation can be a very handy way to ensure your users are entering the type of answer in the format you are expecting in your Google Form questions.
It is relatively hidden option, but it is particularly handy when trying to allow customers to specify a payment amount of money as part of the submission in a Short Answer Question.

Adding response validation ensures your user puts in a proper number format, and you can also make minimums and maximums.
Make sure you add a $ or Money Identifier to the end of the Title of your Short Answer Question. This way, we know the number in the response will be added to the checkout amount.
