	  Hi,
	
	I think that I already made this kind of thing working with a
simple :
	
	
	  <dtml-in "findResults(REQUEST.form)">
	  ...
	  </dtml-in>
	(if "findResults" is the name of your ZSQLMethod component...)

		Ok. I redesigned my zsql method to be much simpler:
		
		 select * from host
		 <dtml-sqlgroup where>
		  <dtml-sqltest name="location1" column="site" type="nb"
optional>
		   <dtml-or>
		    <dtml-sqltest name="location2" column="site"
type="nb" optional>
		   <dtml-or>
		    <dtml-sqltest name="location3" column="site"
type="nb" optional>
		   <dtml-and>
		  <dtml-sqlgroup>
		   <dtml-sqltest name="usetype1" column="UseType"
type="nb" optional>
		   <dtml-or>
		    <dtml-sqltest name="usetype2" column="UseType"
type="nb" optional>
		    <dtml-or>
		     <dtml-sqltest name="usetype3" column="UseType"
type="nb" optional>
		   </dtml-sqlgroup>
		  <dtml-and>
		   <dtml-sqltest name="active" column="Active_Inactive"
type="int"
		optional>
		</dtml-sqlgroup>
		
		My form is a combination of checkboxes:
		   <form action="resultsPage">
		    <table>
		    <tr>
		    <td>Select any of the following combinations:</td>
		    </tr>
		    </table>
		    <table>
		    <tr>
		    <td>Active:</td>
		    <td><input type="checkbox" name="active" value="1"
		checked="checked">Active</td>
		    </tr>
		    <tr>
		    <td>Site:</td>
		    <td><input type="checkbox" name="location1"
value="aus">Austin </td>
		    <td><input type="checkbox" name="location2"
		value="ca">California</td>
		    <td><input type="checkbox" name="location3"
		value="mass">Massachusetts</td>    
		    </tr>
		    <tr>
		    <td>UseType:</td>
		    <td><input type="checkbox" name="usetype1"
		value="server">Server</td>
		    <td><input type="checkbox" name="usetype2"
value="cad"> CAD</td>
		    <td><input type="checkbox" name="usetype3"
value="base">Base</td>
		    </tr> 
		    <tr>
		    <td><span><input type="submit" class="submitLink"
		value="save"></span></td>
		    </tr>
		    </table>
		   </form>
		
		The only problem I am having is bridging the two in
order to get my
		results. I have a dtml method that I am trying to
process the zsql
		method but I don't think I am doing it correctly.
		
		<dtml-call expr="findResults(location1=location1, ...,
		usetype1=usetype1, ...,active=active)">
		
		 But, with the above if location2 or any of the boxes
are not selected I
		am getting an error that they are not defined. How do I
correct this
		problem?
		
		Thanks You.
