Why am I getting a syntax error for my elif statement?

Below is a copy of my code. I keep getting a syntax error for elif centralLat and centralLong. I don't understand why. I indented everything correctly. The first if easternLat and easternLong works. Why don't the elif statements for centralLong and centralLat, etc work?

For this assignment, I have to check each latitude and longitude for a specific time zone and calculate the happiness score for a timezone. This happiness score is the sum of the sentiment values of tweets in a timezone divided by the number of tweets in a timezone.

Why do I keep getting an error?
