How to require field only when necessary?

Unfortunately, in having some of our users "test" the form, we've run into
another problem.
The "description" field is a required one, so that is indicated on the form
(*) for each of the 8 items. According to one user, they were testing the
ability to order just 1 item. However, it kept throwing an error message
until they put at least 1 character in the description field for each of
the 8 items. That won't work. Generally, most of our users will only be
ordering 1 or 2 items, so they certainly don't want to needlessly be
putting characters in the remaining item description fields, when that
action is of no value.
Suggestions?
Thanks

Hi Robert,

Thanks for reaching out to Jotform Support. If you want your Description Field to be required when necessary, this can be achieved using the Enable/Require Field conditions. This way when your users select one of your items, the description field will only then be required. Let me show you how:

• In the Form Builder, on the orange navigation bar, click on Settings.
• On the left panel, select Conditions.
• Click the Add a new condition button, then select  Enable/Require Field.

You can follow the Conditions below: (This condition is for your Item 2)

Follow the same condition for your other Items, only change the IF Statement for different Items.

This means that when the QTY 2 is filled, the Description Field will be set as required. But, please make sure to disable all your Required fields in your Form Settings since this will be required conditionally.

Here's the result:

You can check out my demo form to see its settings and output.

Give it a try and let us know how it goes.
