Example
<h3>Mid Example</h3>
<cfif IsDefined("Form.MyText")>
<!--- if len is 0, then err --->
   <cfif Len(FORM.myText) is not 0>
      <cfif Len(FORM.myText) LTE FORM.RemoveChars>
      <p>Your string <cfoutput>#FORM.myText#</cFOUTPUT> only has
<cfoutput>#Len(FORM.myText)#</cfoutput> characters. You cannot output
the <cfoutput>#FORM.removeChars# </cfoutput> middle characters of this
string because it is not long enough
      <cfelse>
      
      <p>Your original string: <cfoutput>#FORM.myText#</cfoutput>
      <p>Your changed string, showing only the <cfoutput>#FORM.removeChars#
</cfoutput> middle characters:
      <cfoutput>#Mid(Form.myText, FORM.removeChars, Form.countChars)#</
cfoutput>
