Crystal - If Statement ? Very Basic

Can someone tell where I would enter and structure an If Statement in Crystal to do the following. I am familiar with the statements but not sure where it would go.

I have a Charge Amount and an Overide Amount. I want it to display the charge_amt field only when the overide_amt field is null.

charge_amt and overide_amt are my fields

thanks

Create a Formula field that returns the proper amount field. Then print/display the Formula field on the report. The Formula would contain the following

Code:

---

If IsNull({Your Table Name.Overide_Amt}) Then
  {Your Table Name.Charge_Amt}
Else
  {Your Table Name.Overide_Amt}

---

Thank You Very Much. How can I modify this code so that if the Overide Column is null or = $0.00 ?

If IsNull ({fox_trans_charge.override_amt}) Then
{fox_trans_charge.charge_amt}
Else
{fox_trans_charge.override_Amt}

If IsNull ({fox_trans_charge.override_amt}) Or {fox_trans_charge.override_amt} = 0 Then
...

Thank You but that will just bring back the original data.

Does this not have to be part of a Where Clause?

Can you help me with that. thanks

No, it goes into the report...

It's been too long since I've made a report, but we do this kind of stuff all the time. Another thing you can do it to bring up the properties of the field and make its visibility conditional on any criteria you want.
