Excel how to display text based on values of two cells

Question

I'm looking for a way to display the word "Lumpsum" or "Days" based on Hiring Date.C74 & D74 which gets subtracted into number of days + 1 and gets displayed on the cell H71. If H71 is any number G71 should show as "Days" and if there is an error or the value displays as "-" then it should show as "Lumpsum"

Cells Values are as follows :

1- G71 -

=IF(HD72="-","LUMPSUM",IF(D72="Mob & Demob of 6"" Dewatering Pump","LUMPSUM",IF(D72="Well point","LUMPSUM","DAYS")))

2- H71 -

=IFERROR(IF(D72="Mob & Demob of 6"" Dewatering Pump", F74,D74-C74+1),"-")

3- D72 is a drop down list with these values :

a) Dewatering Pump - G71 should be "Days"

b) 6" Dewatering Pump - G71 should be "Lumpsum"

c) Mob & Demob of 6" Dewatering Pump - G71 should be "Lumpsum"

d) Standby Pump - G71 should be "Days"

e) Well point - G71 should be "Lumpsum"

f) Well Points Buried at site - G71 should be "NOS"
