Can someone help me to make the following formula work.

=IF(H8-$H$7<0.041,H8+$O$21, "")& IF(H8-$H$7<0.0826,H8+$O$22, "")&
IF(H8-$H$7<0.1243,H8+$O$23, "") & IF(H8-$F$7<0.166,H8+$O$24,"")& IF(H8-
$H$7<0.2076,H8+$O$25,"")& IF(H8-$H$7<0.2493,H8+$O$26,"")& IF(H8-$H
$7<0.291,H8+$O$27,"")& IF(H8-$H$7<0.3326,H8+$O$28,"")& IF(H8-$H
$7<0.375,H8+$O$29, "")& IF(H8-$H$7<0.4167,H8+$O$30, "")& IF(H8-$H
$7<0.4583,H8+$O$31, "")&IF(H8-$H$7<0.50,H8+$O$32,
End of day)
