I have the following formula that works just fine, except that I need help
with the formula when G33 is blank. I would like the formula cell (H33) to
remain blank if no value has been entered. Any suggestions?

=CHOOSE(SUMPRODUCT(--($A$1:$A$17=E53),--(G53=$B$1:$B$17),$D$1:$D$17)+SUMPRODUCT(--(E53=$A$19:$A$23),--(G53$B$19:$B$23),--(G53<=$C$19:$C$23),$D$19:$D$23)+SUMPRODUCT(--(E53=$A$24),--(G53=$B$24),$D$24),"Inconsistent","Does
Not Meet","Successful","Excellent","Exceptional","N/A")
