.net build errors

I am a new user for asprunner .net. I am attemting to create our 1st app and I am getting .net errors on the build. I only get the errors when I select use codebehind. It seems to work when I don't select codebehind. I prefer code behind. A sample of the error is:
C:\Inetpub\wwwroot\dotnet\StaffEdit\Staff_edit.aspx.vb(279) : error BC30201: Expression expected.
cmd.Parameters.Add("##FILE_NAME_FIELD_PARAM##", ##FILE_NAME_FIELDTYPE##).Value = DBNull.Value

~

C:\Inetpub\wwwroot\dotnet\StaffEdit\Staff_edit.aspx.vb(283) : error BC30201: Expression expected.
cmd.Parameters.Add("##FILE_NAME_FIELD_PARAM##", ##FILE_NAME_FIELDTYPE##).Value = func.TypeCast("", fldDepartmentCode.Text, "##FILE_NAME_FIELDTYPE##")

~

C:\Inetpub\wwwroot\dotnet\StaffEdit\Staffsearch.aspx.vb(472) : error BC30198: ')' expected.
fldHomeUrl.Text, fld2HomeUrl.Text)

~

C:\Inetpub\wwwroot\dotnet\StaffEdit\Staff_search.aspx.vb(488) : error BC30451: Name 'sWhere' is not declared.
If sWhere.Trim() = "" Then

C:\Inetpub\wwwroot\dotnet\StaffEdit\Staff_search.aspx.vb(492) : error BC30451: Name 'sWhere' is not declared.
 Session("dbGrid_Staff_AdvWhere") = sWhere.Substring(4)

 ~~~~~~ 
Can I use codebehind option with this product?
Thanks
