Please help what did i do wrong?

I messed something up. It was compiling fine and now I get this error. If anyone is really good at marlin. Please look over. If you can give me some advice on how to find what i changed so I can fix it. It would greatly appreciated.

Here is the Error

option enabled in File -> Preferences.

It seems, there is something wrong with this line

...error: expected primary-expression before ')' token
#define min(a,b) ((a)<(b)?(a): (b))

Maybe your version of arduinoIDE doesn't support this code. Ask in Marlins github repo which IDE version to use.
