The function evaluates all of its arguments, left to right, and returns the result of
evaluating the last argument.

Syntax
Evaluate( string_expression1 [, string_expression2 [, ... ] ] )
string_expression1, string_expression2
Valid expressions to be evaluated.
Usage
String expressions can be arbitrarily complex. Note, however, that they are somewhat
more complicated to write because they are inside a string. In particular, if the string
expression is double-quoted, double-quotes inside the expression must be escaped.

<CFIF IsDefined("FORM.myExpression")>
<H3>The Expression Result</H3>
<CFTRY>
<!--- Evaluate the expression --->
<CFSET myExpression = Evaluate(FORM.myExpression)>
<!--- Use DE to output the value of the variable, unevaluated --->
<CFOUTPUT>
<I>The value of the expression #Evaluate(DE(FORM.MyExpression))#
is #MyExpression#.</I>
