Can anyone help me figure out why I am getting this error? I am trying to manually write an Array Formula.

.Range(.Cells(bytDays + 4, 1), .Cells(bytDays + 4, 14)).Formula = Array(vbNullString, vbNullString, "=IF(RC[-2]=0,""0"",(RC[-2]+RC[-1]/60))", "vbNullString, vbNullString, "=IF(RC[-2]=0,""0"",(RC[-2]+RC[-1]/60))", _
                "=IF(RC[-6]=0,"0",(RC[-1]/RC[-4]))", "=TEXT(RC[1],"dddd")", vbNullString, "=IF(RC[-9]=0,"",(RC[-4])/(RC[-7]))", vbNullString, vbNullString, _
                "=IF(RC[-2]=0,"0",(RC[-2]+RC[-1]/60))", =IF(RC[-13]=0,"",(RC[-1])/(RC[-11]))")

I do not understand why the word IF is highlighted when I Debug. I have many IF formulas and they seem to be ok. This is what is highlighted but it's just the word IF that seems to be an issue. 
"=IF(RC[-2]=0,""0"",(RC[-2]+RC[-1]/60))", _
