The problem is that the page is parsed before it's executed, and CF doesn't
know which branch of your CFIF will execute at runtime. Since your closing
CFFORM tag needs an opening CFFORM tag, and CF doesn't know whether there
will actually be an opening CFFORM tag when the parser is doing its thing,
you get a parsing error. You can fix that parsing error by either placing
both your opening and closing CFFORM tags within your conditional logic:
<cfif ...>
<cfform ...>
...
</cfform>
<cfelse>
<cfform ...>
...
</cfform>
</cfif>
or you can put both CFFORM tags outside your CFIF:
<cfif ...>
<cfset MyAction = "emp_add_action.cfm?myvariable=true">
<cfelse>
<cfset MyAction = "emp_add_action.cfm">
</cfif>
<cfform action="#MyAction#" ...
...
</cfform>
Alternatively, you could just send this as an extra form variable.
