I see several problems with your current formula field syntax — the following are invalid:

{{RPS_Deposit_Based_Commission_First_Year__c != null }}
{{RPS_Deposit_Based_Commission_Renewal_Yrs__c != null }}
{{RPS_Deposit_Based_Commission_Transfer__c != null }}

should be

{{RPS_Deposit_Based_Commission_First_Year__c}} != null
{{RPS_Deposit_Based_Commission_Renewal_Yrs__c}} != null
{{RPS_Deposit_Based_Commission_Transfer__c}} != null

See if that changes anything.
Alternatively you could check for something like > -1, which would be false if the field is either null or not present but true if the field has a 0 value.

thank you Zach…that was it!

actually I take it back…that was not it. Here is the updated formula… IF({{RPS_External_Transfer_Amount__c}} >= 20000000,true, IF({{RPS_Expected_Number_of_Participants__c}}>=1000,true, IF({{RPS_Expected_Number_of_Participants__c}} < 10 && {{RPS_External_Transfer_Amount__c}} >= 40000 && ({{RPS_Deposit_Based_Commission_First_Year__c }} >-1 || {{RPS_Deposit_Based_Commission_Renewal_Yrs__c }} > -1 || {{RPS_Deposit_Based_Commission_Transfer__c}} >-1),true, IF({{RPS_MVE_Amount__c}}>=100000 || ({{RPS_MVE_Amount__c }} > {{RPS_External_Transfer_Amount__c}} * 0.05) ,true,false)))) When any of these fields are empty or not in the model the formula still evaluates to true which it should not. RPS_Deposit_Based_Commission_First_Year__c RPS_Deposit_Based_Commission_Renewal_Yrs__c RPS_Deposit_Based_Commission_Transfer__c

I believe your formula is written so that if any of those fields return true, the formula will return true. That’s what the OR statements mean.

If you want to return true only if all of the three fields are present, use AND statements.

thanks Matt…I actually want do want it to return true if any even one of those fields is null

Try testing just this part of your formula, and see if you’re getting the results you want:

IF(({{RPS_Deposit_Based_Commission_First_Year__c }} >-1 || {{RPS_Deposit_Based_Commission_Renewal_Yrs__c }} > -1 || {{RPS_Deposit_Based_Commission_Transfer__c}} >-1),true,false)

In words, this formula says:

If ((Field1 is NOT null) OR (field2 is NOT null) OR (field3 is NOT null)) return true. otherwise, return false.

If that’s not what you want, you need to change your formula.
