Hi, I have about 25 text boxes for text inputs in one of the screens. I need to create a logic to show an error in case any of the textboxes are left empty. Is there any way i can create that for all text boxes in one go? Is there such a thing?

Yes. You can loop through all text inputs using [Any Component](https://docs.thunkable.com/blocks/advanced-app-features/any-component-blocks) blocks. Before the loop, set a variable called foundEmpty to false. Inside the loop, use the `is empty` block and if that’s true, change foundEmpty to true and exit the loop.

If you have trouble with this, post a link to your project or a screenshot of what you’ve tried.
