**whatsyourvape**Can I use conditions to require that a specific multiple be used for a quantity?

In other words, Can I require that a person order a quantity that is a multiple of a certain value?

**Mike_G**Using conditions, it is possible to create an equation and check if a number entered on a field is a multiple of a certain number/value.

After that, you can have another condition to show/hide the submit button based on the result of the equation. You can also create a message using Text (HTML) field that will show if the conditions are not met.

Here's a sample form — https://form.jotform.com/80164693496972

Feel free to create a clone version of that form in your account so you can inspect it.
