Loop to generate TextBox

What I have is a frame which has a few text boxes within and a scroll bar. This is used to save space on my form. The problem is coming down to coding. What I could do is create 20-30 instances of these text boxes and when a previous box.value is not blank, the next box in line would be .visible = true. As you can see, after 20 of these, this will simply be a very tedious task - to assign a variable to all of the boxes and then individually create a small code to make each box thereafter visible.

I was hoping there would be some way to craft a code which would generate a new box based on the scenario when a previous box has been typed in. One of the larger issues I'm not sure how it could work is where the box is generated (I want it to be the same distance below the previous boxes before it).

Thanks for any tips.
Regards.
