nested if formula

[ABetha]

I am trying to summarized a nested if formula I am not getting the numbers that I am looking for.

I believe that I am on the right track with this

if {@outofWarranty} = 0 and {@DuplicateRep 2} = 0 and {@Hours } = 0 and {@visit} = 0 then
1
else
0

here are the contents of the following formulas
{@outofWarranty}
if {@warrend} < {vSerialNo.Date} then
formula = 1
else
formula = 0
end if

{@DuplicateRep 2}
if not onfirstrecord and {vSerialNo.Date} = previous({vSerialNo.Date}) and {@DuplicateRep} = "dup" then
1
else
0

{@Hours}
if val({vSerialNperation})>= 1 then
formula = 0
else
formula = 1
end if

{@Visit}
if ({vSerialNo.ReportDate}-{vSerialNo.Date} >= 180) then
formula = 1
else
formula = 0
End if


I then want to take a total of the credit
I then use the three formula structure
Summary Formula

whileprintingrecords;
numbervar Sumcredit;
if {@outofWarranty} = 0 and {@DuplicateRep 2} = 0 and {@Hours } = 0 and {@visit} = 0 then
Sumcredit :=Sumcredit + 1 ;

Display
WhilePrintingRecords;
numbervar Sumcredit;

Reset
WhilePrintingRecords;
numbervar Sumcredit;
if not inrepeatedgroupheader then
Sumcredit := 0
