    trim each element and check to see if the length is greater than 0.

    Do this before you even create and populate the array.

    It gives this kind of error  when I am trying to check the length

    Element 7 is undefined in a Java object of type class coldfusion.runtime.Array.

    The error occurred in E:\www\test\codes.cfm: line 727
    725 :                     <td>#da[1]#</td>
726 :                     <td>
727 :                     <cfset done = #trim(ca)#>
728 :                     <cfif Len(done) is 0>
729 :                     hi

    That error is telling you that you are referencing the 7th element of a 6 element array.

    I.E. ca[7] does not exist.
