Conditional formatting with formula referencing range in different cell

Hi,

It's probably pretty simple, but I'm already breaking my head over it for a couple of hours now.

I want to set a conditional format to cell A1 with a value in cell P1
When the value in P1 is between 0 and 10 the conditional value in P1 should be set.

Note
cell A1 is also set with a conditional format to put a border around it when there's a value in A1 (cellvalue is not equal to " ")
So the formula referencing P1 would be a second condition.

Thanks!
