How can I match my subscripted assignment dimensions?

I'm trying to retrieve multiple securities from Yahoo! by using a loop then storing the results in a matrix. However, I keep encountering the error, "Subscripted assignment dimension mismatch." How can I fix this?

Here is my script:

c = yahoo;

ticker = {'GOOG' 'IBM' 'TWTR'};
fromdate = { 735766, 735767, 735783};
todate = { 735783,735783,735783};

for i = 1:3
Price.(ticker{i}) = fetch (c,ticker(i),'Adj Close',fromdate{i},todate{i});
temp = Price.(ticker{i});
ClosePrice(:,i) = temp (:,2);
end

EDU>> extwo

    Subscripted assignment dimension mismatch.

      Error in extwo (line 10)
      ClosePrice(:,i) = temp (:,2);

Any help would be great! Thanks,

Matt
