You enclose CFScript regions inside <CFSCRIPT> and </CFSCRIPT> tags. No other CFML tags are allowed inside a CFSCRIPT region.
A CFSCRIPT tag block must contain at least one CFScript statement, and comments are not considered statements. If there are no statements, you should comment out the entire CFSCRIPT block (including its enclosing <CFSCRIPT> and </CFSCRIPT> blocks) with CFML comment tags.
You can read and write ColdFusion variables inside CFScript, as shown in this example:
<CFOUTPUT QUERY="employees"> <CFSCRIPT> //`testres' is a column in the "employees" query if( testres EQ 1 ) result="positive"; else result="negative"; </CFSCRIPT> <!--- The variable result takes its value from the script region ---> Test for #name# is #result#. </CFOUTPUT>
