Error Compiling With Arduino Micro

Trying to follow example of Stalker Guard project. When I compile, I get no syntax errors but get only "error compiling" message. I am new to using Arduino micro board and only have limited experience but successful with Uno board. Could someone suggest a few areas for troubleshooting my compiling error? Board is not connected to computer during the compile but i have chosen micro board and serial COM other than the default COM.

I do not know if I have chosen the right programmer option.

What is this link please.

Read the how to use the forum sticky for guidance but we need to see the error message copy and paste it between code tags.
