Coding the file string and error bars?

Hi Guys.
Finally getting around most of the quirks in Screen 4, thanks to ya'lls help on this site.

To do a screen design fresh from the start, how would I include these two or three sections in the new screen?
I have been opening two instances of Screen 4 and using one to look how Mach's standard screen buttons are coded.
These text areas are done differently somehow. Are they VB scripted or something? If so, how do I go about incuding them on my new screens?
Thanks.

I will just share some of the things I used to get going in Screen 4.
Make the background image small enough that scrolling isn't needed. Lock the background image in place. When entering any new buttons, turn off the background image with the switch up top.
Then turn back on to size and place the buttons over the image.
Don't lock buttons in place. Work on one button at a time. Save your work often.
These things have helped me alot.
Thanks.
