Greetings! Does anyone know the best way of understanding extremely
complicated Nested IFs in formulas in VBA? Consider the following code which
I believe I completely debugged over a year ago:

Application.Goto Reference:="R1C23:R1C23"
ActiveCell.FormulaR1C1 = "0.0"
Range("W2:W" & LstRowData).FormulaR1C1 = _
"=IF(RC[-20]=""XIssuer name: "",0.0, " & _
"IF(AND(RC[-12]<""10 - Acquisition or disposition in the
public market "", RC[-12]<""11 - Acquisition or disposition carried out
privately "", RC[-12]<""30 - Acquisition or disposition under a
purchase/ownership plan ""),R[-1]C, " & _
"IF(AND(RC[3]=""SR"",RC[-11]0.0,RC[-13]=""Direct Ownership
:""),R[-1]C+RC[-16]*RC[-11]*RC[-10]*(1.0 + RC[-11]/RC[-8]), " & _
"IF(AND(RC[3]=""xc"",RC[-11]0.0,RC[-13]=""Direct Ownership
:""),R[-1]C+R2C10*RC[-16]*RC[-11]*RC[-10]*(1.0 + RC[-11]/RC[-8]), " & _

"IF(AND(RC[3]=""SR"",RC[-11]0.0),R[-1]C+R2C12*RC[-16]*RC[-11]*RC[-10]*(1.0 +
RC[-11]/RC[-8]), " & _

"IF(AND(RC[3]=""xc"",RC[-11]0.0),R[-1]C+R2C12*R2C10*RC[-16]*RC[-11]*RC[-10]*(1.0 + RC[-11]/RC[-8]), " & _
"IF(AND(RC[3]=""SR"",RC[-13]=""Direct Ownership
:""),R[-1]C+RC[-16]*RC[-11]*RC[-10]*(1.0 - RC[-11]/(RC[-8] - RC[-11])), " & _
"IF(AND(RC[3]=""xc"",RC[-13]=""Direct Ownership
:""),R[-1]C+R2C10*RC[-16]*RC[-11]*RC[-10]*(1.0 - RC[-11]/(RC[-8] - RC[-11])),
" & _
"IF(RC[3]=""SR"",R[-1]C+R2C12*RC[-16]*RC[-11]*RC[-10]*(1.0 -
RC[-11]/(RC[-8] - RC[-11])), " & _

"IF(RC[3]=""xc"",R[-1]C+R2C12*R2C10*RC[-16]*RC[-11]*RC[-10]*(1.0 -
RC[-11]/(RC[-8] - RC[-11])), " & _
"IF(AND(RC[3]=""DIR"",RC[-11]0.0,RC[-13]=""Direct Ownership
:""),R[-1]C+0.5*RC[-16]*RC[-11]*RC[-10]*(1.0 + RC[-11]/RC[-8]), " & _

"IF(AND(RC[3]=""DIR"",RC[-11]0.0),R[-1]C+0.5*R2C12*RC[-16]*RC[-11]*RC[-10]*(1.0 + RC[-11]/RC[-8]), " & _
"IF(AND(RC[3]=""DIR"",RC[-13]=""Direct Ownership
:""),R[-1]C+0.5*RC[-16]*RC[-11]*RC[-10]*(1.0 - RC[-11]/(RC[-8] - RC[-11])), "
& _

"IF(RC[3]=""DIR"",R[-1]C+0.5*R2C12*RC[-16]*RC[-11]*RC[-10]*(1.0 -
RC[-11]/(RC[-8] - RC[-11])),R[-1]C))))))))))))))"

I have found this code extremely difficult to understand and modify. Every
time I want to make a small change in one of the deeper nested IFs, I can
count on it taking over 30 minutes. Is there a better way of expressing the
above code? A better and easier to understand way of accomplishing the
function of the above code? I am open to any and all suggestions. Thanks in
advance for your help.
