Your two if statement are identical, which makes me think you've just made an error copy/pasting your script.
In general, every 'if' statement requires a corresponding 'end if' statement. There must be one 'end if' for every 'if'.
Additionally, you can use 'else if' make a series of mutually-exclusive tests - i.e. if the first does not match, check another, and another, until you either find a match or run out of options. 'else if' statements don't have their own 'end if', but match with the original 'if' statement.
For example, single test:
if (someVariable is true) then
  -- do some actions, e.g.:
  display dialog "Yes"
end if
Single test with single 'else':
if (someVariable is true) then
  -- do some actions, e.g.:
  display dialog "Yes"
else
  display dialog "No"
end if
In this case, if someVariable is not true you get the 'No' dialog. Compare this to the first example, where you wouldn't get any response at all.
Multiple cases:
if (someVariable is true) then
  -- do some actions, e.g.:
  display dialog "Yes"
else if (someVariable is false) then
  display dialog "No"
else
          display dialog "I have no idea what it is"
end if
In this example you test if someVariable is true.
If it is then you perform the first action (report 'Yes') and the script ends
If it is not, then you perform a second test to see if it is false. If this test passes then you report 'No' and the script end.
If someVariable is neither true nor false (e.g. maybe it's a numeric variable or a string) then the 'else' clause kicks in and you get the 'no idea' response.
