Error: Unknown constructor 'PricebookEntry.PricebookEntry()'

I'm trying to adapt some code from Jeff Douglass that I know works, but my changes break it.  For starters, I get the error "Unknown Constructor 'PricebookEntry.PricebookEntry()'" and I can't even find where this refers to.  Any help appreciated, thank you.

 

  <apex:page controller="PricebookEntry" sidebar="false">
 
  <apex:form >
  <apex:pageMessages id="errors" />
 
  <apex:pageBlock title="Find A Product" mode="edit">
 
  <table width="100%" border="0">

          document.getElementById("product2ID").value,
          document.getElementById("Name").value,
          document.getElementById("description").value,
          document.getElementById("unitprice").value
          );
      }
      </script> 
 
      <apex:actionFunction name="searchServer" action="{!runSearch}" rerender="results,debug,errors">

Can you provide the controller code as well,

So that it would be helpful to understand the basic logic behind your code.

Thank you.

Salesforce support comes through!  They fixed the code.  I will post if anyone asks.
