I WOULD LIKE TO ADD VIDEOS TO TABLES. HOW WOULD I GO ABOUT DOING THAT?

You have to use script to do this because QuickBase greatly restricts what HTML tags are allowed in text fields. 

Here is a working demo using the IOL technique:

Pastie Database

You can add your own video to the demo:

Notes:

(1) The code uses HTML backticks for string interpolation.
