Command to insert or update database error

Question

I'm using DW CS4. Every time I create a new command to insert or update a record the generated code is invalid. The error is at the line that suppose to have all variables just before the adodb command and looks like this:
<%
' IIf implementation
Function MM_IIf(condition, ifTrue, ifFalse)
  If condition = "" Then
    MM_IIf = ifFalse
  Else
    MM_IIf = ifTrue
  End If
End Function
Dim insNewCalComm__@@varName@@
insNewCalComm__@@varName@@ = "@@defaultValue@@"
If (@@runtimeValue@@ <> "") Then
  insNewCalComm__@@varName@@ = @@runtimeValue@@
End If
%>

     try {
               executeInsert();
          catch(Exception e){ /*duplicate key error if exists*/
          try {
               executeUpdate();
          catch(Exception p){ /*another error*/
          System.out.println( e.getMessage());
          System.out.println( p.getMessage());
     }
