I have created a worksheet that works splendidly involving Data Validation
Drop Downs (DDVD). There are many formulas in this workbook. All was well
until my boss told me that he prefers "the little hand instead of having to
click on the cell to select the item he wants." Meaning a combo box
drop-down menu. So I went back, deleted the DVDD's and created DD's from the
Forms/Combo Box toolbar icon. Now my formulas respond with the error #REF!
UGH! Here is one example of how the formula now looks:

=IF(#REF!=$A$2,3.5*$C$2*IF($G$2=1.5,1.25,1)+6.45* $C$3*IF($G$2=1.5,1.25,1)+6*$C$4*IF($G$2=1.5,1.25 ,1)+9.25*$C$5*IF($G$2=1.5,1.25,1)+16*$C$6*IF($G$2 =1.5,1.25,1)+4.27*$C$7*IF($G$2=1.5,1.25,1))+IF(# REF!=$A$3,5*$C$2*IF($G$2=1.5,1.25,1)+8.05*$C$3*IF ($G$2=1.5,1.25,1)+7.25*$C$4*IF($G$2=1.5,1.25,1)+ 12*$C$5*IF($G$2=1.5,1.25,1)+22*$C$6*IF($G$2=1.5, 1.25,1)+6*$C$7*IF($G$2=1.5,1.25,1))+IF(#REF!=$A$4 ,3.35*C2*IF($G$2=1.5,1.25,1)+6.4*$C$3*IF($G$2=1. 5,1.25,1)+5.55*$C$4*IF($G$2=1.5,1.25,1)+9.5*$C$5* IF($G$2=1.5,1.25,1)+15.45*$C$6*IF($G$2=1.5,1.25, 1)+3.7*$C$7*IF($G$2=1.5,1.25,1))+IF(#REF!=$A$5,4. 5*$C$2*IF($G$2=1.5,1.25,1)+8.05*$C$3*IF($G$2=1.5 ,1.25,1)+8.85*$C$4*IF($G$2=1.5,1.25,1)+13*$C$5*IF ($G$2=1.5,1.25,1)+22*$C$6*IF($G$2=1.5,1.25,1)+4. 5*$C$7*IF($G$2=1.5,1.25,1))

Wise-cracks aside (I'm sure I could have used a VLOOKUP but at the time was
more comfortable with Logic formulas)
Any way of changing the DVDD's to Combo box DD's without having to
re-write/edit all the formulas??

TIA!
