First things first, log into your Airtable account. You can either start fresh with a new base or open up an existing one where you want to add some conditional logic to your forms.

Next, set up the fields in your base that you'll be using in your form. Make sure all the fields you need, whether for conditions or inputs, are properly defined in your table. It's like setting the stage before the big show!

Now, click on the "View" dropdown menu in the top left corner of the screen. Switch to the "Form" view, or create a new form view if you don't have one yet. Easy peasy.

In the form view, you'll see the form builder on the right side of the screen. This is where the magic happens. You can design the form fields and layout here.

Drag and drop the fields from your table into the form. Arrange them in the order you want them to appear. It's like arranging furniture in a room—make it look nice!

Click on the field you want to add conditional logic to. In the field settings panel, look for the option to add conditional logic. It might be labeled something like "Show Field Only When" or similar.

Now, define the rules for when the chosen field should appear. For example, you might set it to "Show this field when [Field X] has the value [Y]". You can even use AND/OR logic to create more complex conditions. Fun, right?

After setting up the conditions, preview the form to make sure everything works as expected. Fill out the form like a user would and check that fields appear or hide according to your rules. It's like a dress rehearsal.

Once you're happy with how everything works, save your form. You can now share the URL with your audience or embed it into a website or email.

And don't forget to periodically review and test your form, especially if you make changes to the underlying table structure. You want to make sure the conditional logic still works perfectly.
