s7 1200 datablock retaining values

Hi!

I've just discovered a problem with my datablock.
I have some values that I wan't to be save even if the power break.
So I have a DWORD that monitor the number of starts. I have it retaining.
But after the power break the DWORD goes to 0 because this is the initial value of the DWORD. How should I be able to have this DWORD retain over power breaks when the PLC always set it to 0 at startup?

Ahhh, I had the memory on a counter value. This was of course reseted to 0 everytime an startup was made. My bad =)
