How to find the unique value and display it in relevant cell

I have a list of 7 values which are all '0' except for one of them. The different values are displayed below:

06:00-08:00
08:00-10:00
10:00-12:00
12:00-14:00
14:00-16:00
16:00-18:00
20:00-22:00

Only one of these values will be displayed within the 7 cells but can change position if a selection from a list changes.

The current situation looks like this:
0
0
0
0
0
16:00-18:00
0

i want 16:00-18:00 to be selected from the list and placed in the cell P15. but the different value can be higher in the list or lower or even change to a different value

Thankyou

it doesnt seem to be working,

my list is in the cells L22:L28

would it help to make a list of the possible data as in:

06:00-08:00
08:00-10:00
10:00-12:00
12:00-14:00
14:00-16:00
16:00-18:00
20:00-22:00

and then see if one of them matches with a number in the list column that contains 6 zeros and then one of them numbers and then display it in a cell?

that's worked now! thankyou!
