Isn't it always those blasted semicolons? 
At my work someone from the graphics dept spent hours on some CSS issues that were eventually traced down to a single comma that had no business being there.
Making sense of the error messages is another skill, the computer has no theory of mind so it can only tell you what it thinks is wrong with the code, but it has no idea what you're trying to achieve with it. After a while you'll learn to interpret "help I didn't expect this code here" to mean "you forgot to close off a section".
