Flash Form talking to cold fusion

["Robert-Flash" <webforumsuser@xxxxxxxxxxxxxx>]

I am using CFGRID to display the results of a SQL query. 
 I want to allow the user to select items from the list results and add the 
choices to a session variable array.

 <cfgrid name="AudioInfo" 
                        colheaders="yes" 
                     query="getAudioList" 
                     selectmode="row"
                     height="300" >

 The variable is SESSION.SongList, when I select a rew from the list by 
clicking on it, I want to add the variable #Song_No# to the Array 
SESSION.SongList[x][2] .

 Any suggestions?
