decontructing a coldfusion array loop

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)

enter image description here

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>

Solution

  • figured out it should go as: items = [['M,'M'],['F','F']]
