Why does the following code not output "Error" if the form is submitted with a blank field? Does Len only evaluate numerical values?
<cfif NOT Len(Trim("Form.myField"))>
<cfoutput>Error</cfoutput>
</cfif>
The following also does not evaluate as expected:
<cfif Len(Trim("Form.myField")) IS 0>
<cfoutput>Error</cfoutput>
</cfif>
HTML:
<input type="text" name="myField" value="">
