'Missing return Statement' error - what am I doing wrong?

'Missing return Statement' error - what am I doing wrong?

Here is a very simple function I am writing.  I cannot save it due to a 'missing return statement' error.   There is a return statement there.  What is still missing?


string mjw.Secs2Time(int Secs)
{
if(Secs  <  10)
{
    return "TEST";
}
}

I have been working on this DB for about a week now and and getting a bit fed up with my lack of progress at learning it.  Grr!!
