Variables not changing in program on TI-82

[bwarren97]

I use my TI-82 grapics calculator quite a lot (usually for programming), and I'm aving a problem with the variables, primarily the "Y" variable. When I put a store command for a real variable in a program, the calculator stores "0" to it no matter what. The problem usually occurs during the first 30 seconds of program execution. I try entering the command several times, and it still doesn't work right. What I'm mainly worried about is the fact that it hasn't done this when I first bought it.

Will it get worse?
Can I do anything to fix it?
Does this indicate a serious problem elsewhere?

i doubt that this is the right section for this but anyway... try contacting the manufacturer and see if they can help you or google

Which section should I put this in?
