Use a Python IDE and debugger. I recommend PyDev, but YMMV.

Why globals? Why so many?

DRY.
[latit, longt] = [data['Data'][0][key]
for key in ['Latitude', 'Longitude']]
There may be even more efficient ways. Certainly the value of data['Data']
can be stored in a variable.

Shouts out for applying DRY.

["{0} at {1}".format(user1, i[0]) is recommended instead:

The indentation of the last quoted line is – as posted – one space to the
left of that of the previous line. That is a syntax error in Python as the
“if” statement is 8 columns to the left instead. Perhaps you have mixed
tabs and spaces and that got lost while posting; in any case, this is not
the original code, so all bets are off.
Also, 8 spaces per indentation level is too much; it certainly is too much
to be posted to Usenet where there is a customary limit at the 80th column.
An indentation of 4 spaces per level is recommended for Python code. If the
code still extends beyond the 80th column, you should use a line
continuation escape sequence if that is syntactically necessary (it is not
in my suggestion above).
