Horse Racing Odd's Line Formula

I have odds line numbers on this excel sheet which is the VL column. I'd like to be able to scratch a horse, (delete a horse from the sheet) and the odds line (VL column) will update to the new value after the horses is scratched from this sheet.

Now I do this in a program that uses VBA and transports this info to Access, where then I export to Excel to this sheet.

Here's the formula I use for the odds line...

#EQUAL(#COLVAL(51),1, .00001)*((#COLVAL(53))-(#COLVAL(53)*.4))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),2, .00001)*((#COLVAL(53))-(#COLVAL(53)*.25))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),3, .00001)*((#COLVAL(53))-(#COLVAL(53)*.10))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),4, .00001)*((#COLVAL(53))+(#COLVAL(53)*.05))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),5, .00001)*((#COLVAL(53))+(#COLVAL(53)*.10))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),6, .00001)*((#COLVAL(53))+(#COLVAL(53)*.25))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),7, .00001)*((#COLVAL(53))+(#COLVAL(53)*.40))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),8, .00001)*((#COLVAL(53))+(#COLVAL(53)))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),9, .00001)*((#COLVAL(53))+(#COLVAL(53)*1.3))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),10, .00001)*((#COLVAL(53))+(#COLVAL(53)*1.6))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),11, .00001)*((#COLVAL(53))+(#COLVAL(53)*1.9))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),12, .00001)*((#COLVAL(53))+(#COLVAL(53)*2.2))/(#COLVAL(50))+
#EQUAL(#COLVAL(51),13, .00001)*((#COLVAL(53))+(#COLVAL(53)*2.7))/(#COLVAL(50))

I added a couple of columns in the excel sheet to occomadate this formula which should work if coded into excel properly. Notice the (50), (51), (53) numbers.

(50) = TC in this excel sheet
(51) = 2V in this excel sheet
(53) = TCa in this excel sheet
VL column is where this formula updates to.

I have one other minor problem with something else, but so not to confuse, I'll mention it later.
