Basically, you set a function within a string where the function is
surrounded by pound signs. I'm using double there as it's a CFSET but if
that string was in a DB field, you would use single.
When you evaluate the string, you do a double set of quotes (single then
double or visa versa) with the variable within pound signs. This has a
multi-evaluation effect where the variable is evaluated normally, then the
string is evaluated which turns the internal variable into its value.
In this case, the value is a custom function call which can contain a query
or anything else I want. All you have to be sure of is the data being
returned.
