Post code to the forum using CODE tags. See this thread:

The error message says the error is on line 66. If you post your code using CODE tags, it numbers them so we can see which line that is. You also could have mentioned which line that is. But if you just go to that line, the error is probably obvious, since the error is telling you exactly what character it expected to see but didn’t.

First of all you better use code tags. The problem is curvy brackets {} after Populate functions declaration and in the end of class.
