Multiple IF statements in a cell

Hi there ! I'm trying to create a template wherein the employees attendance can be monitored.

What I want to do is to have a formula in column S so that if there is a time value in columns M and N, and it equals the value on columns K and L, respectively, then value on column S, shows as "Present".

Then if there is a time value in columns K and L but there are no entries in columns M and N, then column S shows as "Absent".

If columns K and L shows as "VL" and columns M and N are blank, then column S shows as "VL".

If (N:N-M:M)<(L:L-K:K), then column S shows as "Late".

I hope someone can understand what I am trying to do.

I have attached the file so that you can check it.

Try

=IF(AND(K1<>0,L1<>0,LEN(M1&N1)=0),"Absent",IF(AND(K1&L1="VLVL",LEN(M1&N1)=0),"VL",IF(N1-M1<L1-K1,"Late","OTHER")))

Try:

=IFERROR(IF(L2-K2-(N2-M2)=0,"Present",IF(N2-M2=0,"Absent",IF(L2-K2-(N2-M2)>0,"Late",""))),"VL")
