CFspreadsheet issue

Hello, I have a question about CFspreadsheet....

I'm reading a spreadsheet and inserting the data into  a SQL server  DB....everything works fine unless 1 of my columns in the spreadsheet is blank. I'm getting the following error:

Element PHONE is undefined in EXCELQUERYBYNAME.

I tried the put a cfif isdefined to see if that would solve it but no luck....same error message. How can I handle this issue? My cfquery is below:

<cfquery name="insert_Sh_data" datasource="#datasource#">

    INSERT into contactrecord

       (

       contact_date,

       fname,

       lname,
