>Hello, I am having a problem with a listbox click event returning the value of what is in the clicked item. I have rowsource as a select statmentand rowsourcetype as sql. It always returns the first record though. :(

This is from my btcc_multilist.ItemList() code, which reconstructs a comma-delimited list of selected items:
********************************************************************
*  Description.......: BTCC_MultiList.BTC_ItemList: method to return a comma-delimited list of the selected items
*  Calling Samples...:
*  Parameter List....:
*  Created by........: MDA
*  Modified by.......: Nadya Nosonovsky 12/29/1999 04:20:21 PM
********************************************************************
* 11/26/99 NN added into this method an ability to populate btcselarray
* 12/14/99 NN added AllSelected property

* Returns a comma-delimited list of quoted codes corresponding to those selected.
* If none, returns the empty string.
local result, n, k, lnSel, lnLen

* check for empty array special case
if alen(this.btcvalarray) <= 1               && array is empty
     return ''                                   && null list result
endif

result = ''                                        && start with nothing
k=0
lnSel=0

with this

     lnLen=alen(.btcvalarray, 1)
* loop over the array, building list of selected codes
     for n = 1 to lnLen                    && cycle over rows
          if .Container1.List1.selected(m.n)               && this item is selected
               lnSel=lnSel+1 && increment count of selected items
               if k>=1 and ascan(.btcselarray, .btcvalarray[m.n, 2])>0 && This code already exists
* Do nothing
               else
                    result = m.result + iif(empty(m.result), '', ',') ;
                         + '"' + .btcvalarray[m.n, 2] + '"'     && tack on another code
                    k=k+1
                    dimension .btcselarray[k] && redim array
                    .btcselarray[m.k]= .btcvalarray[m.n,2]
               endif
          endif
     endfor

     .btccrit=m.result && store in a property

     if lnSel=lnLen and not .ExcludeFlag && All selected and don't need to be excluded
          .AllSelected=.t.
          m.result='' && empty criterion
     else
          .AllSelected=.f.
     endif
endwith
return m.result                                   && done - return list of selected codes
HTH
If it's not broken, fix it until it is.
