Illegal use of "end" error when I run the following code. What am I doing wrong?

Likely I am missing something obvious...

 for n = 1:2015
    aggRF(n-1) = (-1.3e-6.*((CH4(n)-CH4(1))/2)-8.2e-6*n+.043)...%CH4
    *(sqrt(CH4(n)-sqrt(CH4(1))))...
    +9-8.0e-6*((CO2(n)-CO2(0))/2)+4.2e6*((N2O(n)-N2O(1))/2)...%N2O
    -4.9e-6+.117*(sqrt(N2O(n)-sqrt(N2O(1))))...
    + 0.25*(CFC11(n) - CFC11(1))... %CFC_11
    + 0.32*(CFC12(n) - CFC12(1))... %CFC_12
end

The final line

 + 0.32*(CFC12(n) - CFC12(1))... %CFC_12

ends in dot dot dot (indicating it continues on the next line), when it should end in semicolon

 + 0.32*(CFC12(n) - CFC12(1)); %CFC_12
