How can I figure out every first and third record to use css styling.  I need to do 3 items per row, so I need to identify the first and third of every row in a loop.

If you just want to create a new row every three items use MOD 3. A simple demo example with tables:

<table>
<tr>
    <cfoutput query="someQuery">
        <td>#currentRow#</td>
        <!--- start a new row every three cells --->
        <cfif currentRow MOD 3 EQ 0>
            </tr><tr>
        </cfif>
    </cfoutput>
</tr>
</table>


Otherwise, can you give an example of what you mean? ie Do you mean every other row?

row 1:   find this row
row 2:   ignore
row 3:   find this row
row 4:   ignore
row 5:   find this row
row 6:   ignore

EDIT: If yes, just change the CF code to "currentRow MOD 2 EQ 0". Another option is jQuery's "odd" selector:

Basically I need to do something like this:

<div class="row">

 1   2    3

</div>
<div class="row">

4    5   6
</div>
<div class="row">
7      8
</div>


so i need to start every row with
<div class="row">  and on every third record close it with </div>

Just figure what the MOD is on the 1st and 3rd row and add a CFIF for both.

<cfoutput query="someQuery">

     <!--- when it's the 1st row the remainder is always 1--->
     <cfif currentRow MOD 3 EQ 1> <div class="row"></cfif>

    ... do stuff here ...

     <!--- if it's the 3rd row the remainder is always 0 --->
     <!--- also close the DIV when it's the last row in the query --->
     <cfif currentRow MOD 3 EQ 0 OR currentRow EQ someQuery.recordCount> </div></cfif>

</cfif>

Glad it helped. Btw, not sure if you saw the edit, but I added an extra condition to close the <div> when it's the final row of the query too.
