You should not use the INPUT command to create a graphic background screen. The INPUT command stops or pauses program execution, so you can't write text over the INPUT screen using TEXTOUT_P. The text you are writing in the screens shot is just the edit line for the INPUT textbox for variable D.

If you want to create your own INPUT screen, take a look at the AASHTO-93 1.0 app located on hpcalc.org under HP Prime Science Apps.
