cfloop over array

[bebright09]

I am looping over an array It works fine if all variables are declared in array, I am trying to skip the entire process even if one variable is not declared I tried using isdefined, I tried to use cftry and cfcatch... nothing working any suggestions......

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.

Is there a way to weather an element in an array is decleared ?

arrayLen(ca) would probably tell you all you want to know, but there are other interesting array related functions listed in the documentation as well.
