Condition for Field

How can I make a condition, so that unless the first question has 9 characters (numbers) then the form will not collapse until it does ?

From what I understood you wish to reveal your form only if the field is filled with 9 characters.

From my tests I was unable to achieve this in the same form with conditions.

I believe the best way to achieve this is to create 2 forms.
In the 1st form insert a text box, set validation to numeric, input a value mask ######### and set as required:

You can now edit the warning messages, so they can suit better the situation:

You can now create the 2nd form with a similar text field which we are going to populate with the data inserted in the 1st form.

You can follow this guide so you can activate this property.
