Formula field and nulls question

19 Views

I have a formula field that is filtering out duplicate records (charges). This formula is working perfectly:

If ({vwProdAnalChgs.Account_ID} = previous ({vwProdAnalChgs.Account_ID])) and ({vwProdAnalChgs.Date_Updated}) = previous ({vwProdAnalChgs.Date_Updated}) and ({vwProdAnalChgs.Procedure_Code}) = previous ({vwProdAnalChgs.Procedure_Code}) and ({vwProdAnalChgs.Modifiers}) = previous ({vwProdAnalChgs.Modifiers}) then 0 else {vwProdAnalChgs.Amount}

My question is:

The records do not always include "Modifiers", so the modifier value will sometimes be null.

How do I include Modifier nulls in this equation to make sure I get an accurate filter?

Thanks for any help!
