I have the follwoing IF statement in a formula and I was expected it to never evaluate null which is why the "none" is added at the end. I will be adding more to this formula but I want it to work thus far before I proceed.

If (Not(IsNull({ARACCOUNT.ZZACPENDINS}))) and ({ARACCOUNT.ZZACPENDINS} < 0.00) Then
    "Insurance balance is negative - Notify Kathy"
Else If ({ARACCOUNT.ZZACSPORIGAMT} = 0) Or (IsNull({ARACCOUNT.ZZACSPORIGAMT})) Then
        "No charges"
    Else If ({ARACCOUNT.ZZACSPORIGAMT} - {ARACCOUNT.ZZACSPINSPMT} - {ARACCOUNT.ZZACSPINSADJ} - {ARACCOUNT.ZZACSPPMT} - {ARACCOUNT.ZZACSPADJ}) <> {ARACCOUNT.ARACNBTOTINI} Then
            "Mathematical issue"
        Else
            "None"

You need to test for NULL first.

When Crystal evaluates a formula and  it encounters a NULL in a test other than IsNull , evaluation terminates and the value returned cannot be predicted.

Change your formula to

If (Not(IsNull({ARACCOUNT.ZZACPENDINS}))) and ({ARACCOUNT.ZZACPENDINS} < 0.00) Then
     "Insurance balance is negative - Notify Kathy"
 Else If (IsNull({ARACCOUNT.ZZACSPORIGAMT}))  OR ({ARACCOUNT.ZZACSPORIGAMT} = 0) Then
         "No charges"
  Else If ({ARACCOUNT.ZZACSPORIGAMT} - {ARACCOUNT.ZZACSPINSPMT} - {ARACCOUNT.ZZACSPINSADJ} - {ARACCOUNT.ZZACSPPMT} - {ARACCOUNT.ZZACSPADJ}) <> {ARACCOUNT.ARACNBTOTINI} Then
             "Mathematical issue"
         Else
             "None" 

Open in new window

If any of the fields in the final IF can be NULL you have to handle them also.

If you don't specifically need to see the nulls and just need to keep them from "breaking" your formula, then another option might be to change how CR handles nulls.

 More recent versions of CR have an option in the formula editor to control how CR handles nulls in a specific formula.

 Or, you can go to File > "Report Options" and check the "Convert database null values to default" option, but that will affect just about every formula in the report, so if there are any other formulas where you actually need to see null values, you may not want to use that setting.
