Google spreadsheet 2 rows 1 cell formula

I've got a Google spreadsheet that looks like this:

Start time   |    End Time   |  Time difference
-------------+---------------+-----------------
    11:30:00 |    12:45:00   |     1,25     
-------------+---------------+-----------------
    09:20:00 |    10:30:00   |  
    11:35:00 |    12:00:00   |    #VALUE!
-------------+---------------+-----------------

In the 3rd column I have a formula that calculates the difference in decimal number. 1st row works, can I make it work with the 2nd row without splitting the cell?
