Agreggate sums in sql

I have a table that looks like:
mydate         value       morning   evening
1/1/2013      10            0                1
1/1/2013      25            0                1
1/1/2013      30            1                0
1/2/2013      50            1                0
1/2/2013      10            0                1
1/2/2013      15            0                1

I would like a select statement that would return the sums of the value by morning and evening...
1/1/2013     30           35
1/2/2013     50           25

I tried the following...

  case when morning=1 then sum(value) else 0 end,
  case when evening=1 then sum(value) else 0 end,
FROM MyDataTable
group by mydate, morning, evening
order by mydate

Thanks in advance...
