I'm trying to get my form to remember the last search criteria that was submitted.
I've seen a couple tutorials on this but they were all for your basic text block. My form has drop down lists  and my current code doesnt throw an error but doesnt work either. Example for the minimumPrice field:

<!---prefill form--->
<cfif isDefined("Form.minimumPrice")>
<cfset CLIENT.minimumPrice = Form.minimumPrice>
<cfset prefillminimumprice = Form.minimumPrice>
<cfelseif isDefined("CLIENT.lastminimumPrice")>
<cfset prefillminimumPrice = CLIENT.lastminimumPrice>
<cfelse>
<cfset prefillminimumPrice = " ">
</cfif>
---------------------------------------
and in my form:

<select name="minimumprice">
            <option value="1" selected>#prefillminimumPrice#</option>
            <option value="10000">$10,000</option>
            <option value="25000">$25,000</option>
            <option value="50000">$50,000</option>
            <option value="75000">$75,000</option>
</select>

Any ideas on getting this to work?

Thanks!

just put the form  either in session variable or localScope. And then when you come back to the page do this

<cfif session.form eq form>selected</cfif>

You need to compare the values for each <option> and if the values are the same, mark one as "selected".

<select name="minimumprice">
...
<option value="10000" <cfif YourSavedValue eq 10000>selected</cfif>>$10,000</option>
<option value="25000" <cfif YourSavedValue eq 25000>selected</cfif>>$25,000</option>
....
</select>

... OR if your list is being populated from a query, you could use a cfselect and the "selected" attribute.

<cfform>
        <cfselect name="minimumprice" query="qryPrices" selected="#YourSavedValue#"
             display="PriceTextColumn"
             display="PriceValueColumn" />
</cfform>

Agx one question, I do have a list being populated from a query, and it's all working great except, now on my form how can I get a blank " " option selected at the top of my list if no savedvalue is selected? Like I have a list of cities populated from a query in my dropdown list and I want my first selected option to be "Any City" if there was no savedvalue for this. example:

          <cfselect name = "city" query = "qryCity" value = "city" selected = "#prefillcity#">        
             <option value=" "></option>
         </cfselect>

What you have should work. You'd probably want to add the queryPosition="below" attribute too, so the blank options shows up first

<cfselect queryPosition="below" query="qryCity"  ....etc... >       
             <option value=" "></option>
</cfselect>
