Substring and Form Calculation doesnt works on mobile

I made this form to validate Chilean RUT. In web, works fine but only when I focus on the next field (with Tab button). On Mobile, doesn't work, I cant move focus to the right field to active Form calculation used to validate.

I used "Substring widget" to apply field decomposition.

Form Link: https://www.jotform.com/build/211668800204651

Try with this RUT to validate:

• 30450670-9
• 30450671-7
• 30450672-5
• 30450673-3
• 30450674-1
• 30450675-K
• 30450676-8
• 30450677-6
• 30450678-4
• 30450679-2

Please Help.

Greetings,

In order to trigger the fields without pressing the Tab, you'll have to modify your form a little. I've created a clone of your form. I've added a Time picker field.

Then add another substring widget in the form and create the following condition to create an automated effect.

The paragraph field condition will also get changed to show it as soon as the widget is triggered by the time field.

I have the new fields visible in the form now so you can see how they are working.

You can hide these fields when you are using the forms.

The cloned form link is below.
