Trimming a circular pattern

Hi,

I've got a cylinder and im trying to put 4 holes in the top. I made one hole and just circular patterned it. The problem is, I can only trim the surface of the cylander for the original hole. I cannot get the patterned holes to also be a trimming tool.

So now i have 3 holes that are invisible because I can't get them to work with trim surface. Any ideas?

Thanks,

Rich
