1st question is what do ya'll need, or need to know about my project? before I start asking questions. To assist with removing this error. Code compiles fine. there were two different codes blended together, the first, was similar and worked fine. my new one compiles fine but ******* during upload. Thank you. Fred

The schematic and the code and maybe some photographs.
This is saying that the programmer can't get the correct processor ID. So there is an error in selecting the board to compile if from or your processor is not working for some reason. It could be broken, not being powered up, or miss-wired.
Problem solved, I had (2) programs that uploaded and worked very well individually. When I combined them, it went straight down hill no matter what I tried. After hours of reading I found the problem was probably caused by the reset pin. Others have had similar issues. So I added a 10K pull up from reset to Vcc and a 10uf cap between the Vcc and GND and they all magically went away. No more xxx!=XXXX. Now it's just a matter of some tweaks.
