How can i make it work around if a column is NULL?

I have a table that display some question,

But some may have 4 or 5 question.

Here is my code.

          <cfloop index="i" from="1" to="5">
                 <cfset question = GetEmployeeCSEDepts["csedept_question" & i][GetEmployeeCSEDepts.CurrentRow]>
                       <tr>
                           <td valign="top">
                                  <select name="sltRating#i#" size="1">
                                         <option value="">-- Select Rating --</option>
                                          <option value="5">Exceptional</option>
                                            <option value="4">Exceeds Standards</option>
                                             <option value="3">Successful</option>
                                             <option value="2">Needs Improvement</option>
                                             <option value="1">Unsatisfactory</option>
                                             <option value="0">N/A</option>
                                     </select>
                                  </td>
                         <td valign="top">#question#</td>
                              </tr>
                </cfloop>

So rigth now it display all the quesions but it even questio5 is null.

How will I be able to make it work around to display if csedept_question is NULL to not show

to the user?
