display record after multiple checkbox selected

hai...i got problem here....in my form, i allowed user to select multiple checkbox..all the value for checkbox is default to 'yes'...here is example...


<td><input type="checkbox" name="PJ" value="yes">
Petaling Jaya</td>
<td><input type="checkbox" name="PP" value="yes">
Pulau Pinang</td>


the problem is when i want to display, i got error...the value for every checkbox is located in their own field in database....every checkbox have different field in database...
this is how i done but got error...


<cfif #DOCUMENT_STATERELATED_3# EQ 'yes'><cfset state = 'PJ'>
</cfif>
<cfif #DOCUMENT_STATERELATED_4# EQ 'yes'><cfset state = 'PP'>
</cfif>

for your information, the field in my database is #DOCUMENT_STATERELATED_3# and #DOCUMENT_STATERELATED_3# and the form to display is as below...


<font size="1" face="Verdana"> #state# </FONT>

if i checked only one checkbox. it will display but if i checked multiple checkbox, i got error...how can i fix it?


thank you....

What is the error?
