Problem in using Nested IF-ELSE in Crystal Report formula

Question

Hi Experts ,
                     I am having some problem using  Nested IF-ELSE in Crystal Report formula ,
there is no error in the formula but only one condition is working. other condition is not working
i am using this concept in formula workshop :-
' if{EXCISE_INVOICE;1.Basic Excise Duty BED@10 %}<>0 and{EXCISE_INVOICE;1.Education Cess @2%}<>0 and {EXCISE_INVOICE;1.Secondary Education Cess @1%}<>0 and {EXCISE_INVOICE;1.Central Sales Tax(CST)@2%}<>0
then
Sum ({EXCISE_INVOICE;1.Amount}) + {EXCISE_INVOICE;1.BedAmount@10%} + {EXCISE_INVOICE;1.EcessAmount@2%} + {EXCISE_INVOICE;1.SecCessAmount@1%} + {EXCISE_INVOICE;1.CSTAmount@2%}
else
if {EXCISE_INVOICE;1.Basic Excise Duty BED@10 %}<>0 and {EXCISE_INVOICE;1.Education Cess @2%}<>0 and  {EXCISE_INVOICE;1.Secondary Education Cess @1%}<>0 and   {EXCISE_INVOICE;1.Input VAT@5%}<>0  and {EXCISE_INVOICE;1.Addtional Tax@1%}<>0
then
Sum ({EXCISE_INVOICE;1.Amount}) + {EXCISE_INVOICE;1.BedAmount@10%} + {EXCISE_INVOICE;1.EcessAmount@2%}+{EXCISE_INVOICE;1.SecCessAmount@1% } + {EXCISE_INVOICE;1.VATAmount@5%} +{EXCISE_INVOICE;1.AddTaxAmount@1%(for VAT@4)}
I want that  all conditions  should work and the condition which is applicable there according to formula it display the result,  if i add another condition then it should also work.
kindly tell me the solution of this problem

Try this logic:
if{EXCISE_INVOICE;1.Basic Excise Duty BED@10 %}!=0 and{EXCISE_INVOICE;1.Education Cess @2%} !=0 and {EXCISE_INVOICE;1.Secondary Education Cess @1%} !=0
then
Sum ({EXCISE_INVOICE;1.Amount}) + {EXCISE_INVOICE;1.BedAmount@10%} + {EXCISE_INVOICE;1.EcessAmount@2%} + {EXCISE_INVOICE;1.SecCessAmount@1%}
else
0
+
IF {EXCISE_INVOICE;1.Central Sales Tax(CST)@2%} !=0
then
{EXCISE_INVOICE;1.CSTAmount@2%}
else
IF  {EXCISE_INVOICE;1.Central Sales Tax(CST)@5%} !=0
then
{EXCISE_INVOICE;1.CSTAmount@5%}
+
if {EXCISE_INVOICE;1.Addtional Tax@1%} !=0
then
EXCISE_INVOICE;1.AddTaxAmount@1%(for VAT@4)}
else
0
If not work, try SQL command.
