the code verifies ok but I just get the error message cant upload; any suggestions?
Yes

Hi @savagen. Please add a reply here on this forum topic to tell us which Arduino board you are using.
I see from the output you shared that you have Arduino IDE configured for use with an UNO R3 board. However, something that can be confusing is there are multiple boards with "UNO" in their name:
- UNO (R1, R2, R3) or Uno Mini
- This includes clone/derivative boards as long as they have the ATmega328P microcontroller.
- UNO R4 Minima
- UNO R4 WiFi
- UNO WiFi
- UNO WiFi Rev2
- ...or something else?
We need to be certain of exactly which one you have. The reason is that the problem might be caused by the IDE not being correctly configured for your specific board.
If you aren't sure which one you have, you can provide a picture of the board or a link to the place you bought it from and we'll see if we can identify it.
Board is mega2560 R3.
Which board have you got selected in the IDE ?
its elegoo mega 2560. can't see how I put that in board choices?
thanks!!! that works. much appreciated!
Glad it worked
