This is the code im working on:

I only edited it so that the lcd temp and humidity value would change by 1 to display instead of every 2 seconds and it started giving me gibberish. I undo ed everything reverting it to this iteration that i pasted, and it still would do the same thing. Today I realised after i tried to upload a bare minimum sketch that it wont upload any code on it. Im using a clone R3.
