Looping dynamically over array of structs

Question

I have a shopping cart array of structs running and im trying to dynamically get the data to the screen.

<cfoutput>
<cfloop from="1" to="#ArrayLen(session.shoppingcart)#" index="idx">
    <cfloop collection="#session.shoppingcart[idx]#" item="key">
    <cfset mydata = session.shoppingcart[idx][key] >
    #key# #mydata# #session.shoppingcart[idx][key]#   
    </cfloop>
</cfloop>
</cfoutput>

When I set the mydata variable, i am able to simply apply #mydata# to the page and it displays.

When i try to apply #session.shoppingcart[idx][key]# to the page i get an error stating that it cannot display this as a simple value.

Any ideas on how to get this information to display on screen ?

thanks in advance

You seem to be suggesting that if you output just #mydata#, then it renders fine, but if you output just #session.shoppingcart[idx][key]# then you get an error? Can you add the exact error message (ie: copy and paste it from the screen) to your question. Yuo are also not telling us something or not including all the code because - from your code - mydata and session.shoppingcart[idx][key] have exactly the same values. So will - accordingly - render the same. What have you not told us / not included? — Adam Cameron

Sounds like session.shoppingcart[idx][key] is an object of some sort. You can use <cfdump var="#session.shoppingcart[idx][key]#"> to see the keys and values in that object.
