This post might also be very helpful for debugging problems like this: The 4th thing I wish I knew when I started scripting: What to do when things go wrong.

Script editor also allows matching and highlighting parts of code based on expressions and their fences: Match Parentheses, Brackets, and Braces.

When you put the text cursor on an open parenthesis, the matching close parenthesis highlights. You might need to scroll (with the scrollbars, not the arrow keys) to see the match. Works or the curly braces and square brackets as well, and works from either end.

The New Column hint is probably important; JMP thinks it is still inside a NewColumn( ... function and has not found a matching close parenthesis. It might be 1600 lines above.

You are most likely missing a comma, semi-colon, or parenthesis. These are not always obvious.

Depending on how the JSL is structured, I have found that the code folding feature of the editor is sometimes useful to help narrow the scope of where the problem is. Also, the indentation guides may provide some assistance as well.
