Solved

I am trying to create a formula field in crystal reports combining an if, then, else with an OR.  This seems as if it should be simple, but I am stumped.

I am trying to write a simple IF X or Y then Z else W statement in crystal and while it seems like it should be a simple thing, I cannot get it to work:

formula field ( GiftCount) Code reads:
if {Cash.Cash} > 0 OR
{Payments.Payment} > 0
Then 1
else 0;

a second field (Sum) reads:
sum({@GiftCount})

The problem is sum totals the 1's for all the records where Cash.Cash > 0 but does not include any 1's in the records where Payments.Payment > 0.  Using the built in summary field returns the same result leading me to assume that the field value is not being set to 1 for those later records.

What am I missing here???????

I suspect the problem is you have NULL values in the fields.

Try this
If Not IsNull({Cash.Cash})  AND {Cash.Cash} > 0  then
    1
else If Not Is Null({Payments.Payment}) AND {Payments.Payment}  > 0 then
    1
else
    0;

Try:
if {Cash.Cash} > 0 Then 1
else
if {Payments.Payment} > 0 Then 1
else 0;

Thanks sjjcat, I tried that one (Try:
if {Cash.Cash} > 0 Then 1
else
if {Payments.Payment} > 0 Then 1
else 0;)
and it did not work

mlmcc - I will try yours in the AM.  However, if I create the if/then without the OR (i.e. If Payments.payment >0 then 1 else 0;), it DOES count them as I would expect.  It is only when I add the OR that it seems to want to not work.  I think the fact that each part works individually would suggest that it is not the Null thing but rather something to do with the OR??????

Are you sure the payments field is a numeric field, not text? If text, it may not be able to identify > 0.

If Payments can be NULL when Crystal uses the field it stops execution and returns some value probably NULL or no value thus it doesn't count.

Thanks so much.  Just got back to this and your code did the trick.  Not sure why I have so much trouble writing Crystal formulas as opposed to Access or Excel....

Probably because of the way Crystal handles NULL values in a formula.

Crystal simply stops execution and doesn't really pass a value back.

Any general tips for an Advanced Excel and Access user who is finding Crystal formulas to be a painful experience (despite a large George Peck reference volume)?
