decontructing a coldfusion array loop - coldfusion

Question

I am trying to deconstruct an array loop created by some one and they had instructions on how to call but if I do that value, I am being ended up in an error
Here is the code
<cfloop from="1" to="#ArrayLen(variables.elementObjectsArray[e].items)#" index="o">
<option
<cfif ArrayLen(variables.elementObjectsArray[e].items[o]) eq 3>
class="#variables.elementObjectsArray[e].items[o][3]#"
</cfif>
value="#variables.elementObjectsArray[e].items[o][1]#"
<cfif session.form[e] EQ "#variables.elementObjectsArray[e].items[o][1]#">
selected="selected"
</cfif>
>
#variables.elementObjectsArray[e].items[o][2]#
</option>
</cfloop>
and they mention it to call it this way
// a 2-d array of items if type=select: ["optionValue","optionText","optionClass"]
here is dump of the array (variables.elementObjectsArray[e].items) (from comments)
i did that way, but i am always ending up in error, anyone can guide what i am missing here
This is the error in stack
<td class="struct" onClick="cfdump_toggleRow(this);" style="cursor:pointer;" title="click to collapse">StackTrace</td>
