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>

    What is the error and which line is throwing it? Can you show us a dump of the array (variables.elementObjectsArray[e].items)? Commented Oct 5, 2022 at 20:58

    What is the error you are receiving and on what line (as @CFMLBread asked). A full example we can run on trycf.com that includes the data and code that errors would be very helpful. Commented Oct 5, 2022 at 22:31
  • Taking a wild guess here: session.form[e] might be the problem, because session.form is empty or doesn't have any data für index/key e. This loop can also probably be simplified by using cfloop array index over cfloop from to index. Commented Oct 6, 2022 at 0:17

    You still have not shared the error message that you are getting. We cannot help if we do not know what the error is. This is why it is best to have a full example of code to demonstrate the error. Commented Oct 6, 2022 at 14:45

Reset to default

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