My formula not working

[admin2]

Something strange with my formula. It was working fine earlier, but not now (something changed?)

IF({Date} >= 365, “ :x: ”,
IF({Date} <= 0, “ :x: ”,
IF({Date} < 334, “ :white_check_mark: ”,
IF({Date} >= 335, “ :warning: ”))))

When field is empty or 0 (zero) it still show :white_check_mark:
Why?

I don’t think the condition <=0 would catch an empty field, so I’d try inserting right thereafter:
IF({Date} = BLANK(), "X",
{Date} seems to be the integer type. If that comparison weren’t accepted then try even:
IF({Date} = null, "X",
