Checking for Duplicates in a Field in Other Records

Hey Mark quick question on this.  If I wanted to add another checkbox to my form to control whether to check for duplicates or not could I add the following code to my "Dupicate" formula field?  
The code currently is the following:
var text QUERY = "{6.EX." & [Container Number] & "}";
var bool LookForDuplicates = Size(GetRecords($QUERY))>1;
If([Domestic]=false, $LookForDuplicates)

Could I add the following to add another checkbox called "Consolidated Shipment" to control whether to look for duplicates?
If([Consolidated Shipment]=false, $LookForDuplicates)

Thanks 
Brian
