Wait 3 minutes

[Harty0012345]

Hello, I need help.
My skript is supposed to put down red wool and leave it there for 3 minutes but mine is doing it for a few ticks...
Here is my code:
on block place:
if event-block is red wool:
set location of event-block to {_loc1}
wait 3 minutes
set event-block to air

Thank you!

pretty sure you cant change the location of a block and {_loc1} isn't set to anything

on block place:
    if event-block is red wool:
        wait 3 minutes
        if event-block is red wool:
            set event-block to air

Hi! This seems to work just fine?
