How do you return the value of a dynamic structure key?
If you need to return the value of a structure key where the key is dynamic, you must use bracket notation. Assume myStruct is a structure and you want to get the value of the key stored in a variable, keyname.
<cfset keyname = "foo">
<cfset value = myStruct[keyname]>
<cfset value = myStruct[keyname]>
If the value of mystruct.foo was "Jacob", the variable value will be "Jacob."
