Trying to access Node with variable in Xml

I am trying to put a variable into some code that is being used to access a node in an Xml Doc. Below is what I am trying but I keep getting an error. I am not sure how to make it work.

<cfset bestPrice[2] = "#XmlRateSheet.investor.products.#ProductCode#.rates.ratesdata[4].exp2.XmlText#">

As you can see above #ProductCode# is the variable that needs to be introduced in this code as a variable. Any thoughts on how I can work around this? The error is below.

Thanks,

jfill
