text fild...select and delete command not work

Hi, Santosh.

While the questions above might be better suited for our talented community members, and I'm looking forward to what they will recommend for your specific project file, here's how I would approach this: 

I'd convert your slide to two freeform question slides: one for each text field.

On Form View, you would adjust the following:

1. The correct answer for that field.
2. Which field should be evaluated 
3. Which key you can use to submit, if you are not adding a submit button.
4. The layers you want to use for the feedback.

Here's what that would look like:

I hope this helps!
