62 errors

Check your brackets (runaway errors like this are many times the result of non-complementary bracketing which makes the compiler scream)...most notably in the else near the "//Set up Random". This isn't the only error, but the one which is giving you the majority of them.

okay that basically took care of 61 errors and I have one left

its saying:

user_Life.java:195: illegal start of expression
if(col<=||col>=GRIDSIZE||(r==row && c==col))
^
1 error

if(col<= INPUT SOMETHING HERE ||col>=GRIDSIZE||(r==row && c==col))

You have to input something to test for here. if(col <= || col >= GRIDSIZE) doesnt work.

i can help if you got 69 errors
