This program will not let me get through the whole thing without syntax errors on my TI-84 Plus CE. I got it to work for the "Find Distance" at first but then when I tried to use the other two options it wouldnt work. Can you please tell me how to fix it so I can use all three options for DISTANCE, SPEED, AND TIME?

I also need to make a program for FREE FALL, and PROJECTILE MOTION. Can you help?
