kclessonm98 Probe Posted: 20 Aug 2013 15:35 GMT Total Posts: 3 | I put the ION program in my TI-84 Plus C Silver Edition Calculator. When I try to run the Install, I get a ERROR: INVALID message. Below that it says "Attempted to use a variable or function where it is not valid" I know I put the ION program in the ROM, so that isn't the problem. |
