Answer 1

First off - your code is OK. I took a copy and made minor changes to it just to use a single sheet for illustration:

The problem is likely with your data, specifically the first row. Here's that same example, with some of the "Headers" changed from text into numbers. I believe it is behaving in the bad way you're describing.

One more time, but with the numbers in the header forced to be text. (In the spreadsheet, I input them as '4 and '5 - the leading single quote tells Spreadsheet to treat as text.)

Just take a look at the data types in your first row, and make sure that they are Text.
