Question: I want to have 3 View Controllers; A, B, and C. View Controller A will be where the final value gets displayed, or the Main View Controller. View Controller B and View Controller C will have simple Text Fields as inputs. The values you put into the Text Fields in View Controller B and C will be added together and shown in View Controller A. You will also need to have buttons to implement the action. How can this be done?

For instance, if the user inputs the number 2 in View Controller B and the number 3 in View Controller C text fields, then View Controller A will show the number 5.

Answer: 
You can achieve that in two ways. 
1. You can set controlsList="nodownload" on the video tag to no show the download button

or You can use css to hide the the button. If you post the live video url then it would be easy to debug
I think it would help you Please put it in you Inframe tag.

```
<iframe class="embed-responsive-item" src="{{ asset("/tes.mp4") }}" controlsList="nodownload">

```

Usually It uses within `<video controls controlsList="nodownload nofullscreen">` tag, I think that would work as well!

Cheer you!
