Jeff,

You can process the thisform.Controls[] array and create another array of three columns.

n = 1
for each oCoontrol in this.Controls
   if ( "cbo" $ oControl.Name )
      dimension this.maPairing[n,3]
      n = n + 1
      this.maPairing[n,1] = oControl
   endif
endfor

Now you'd need a little more code to pair the right items up, based on maybe the rest of the Name or the .Tag field.

Holding object references to contained objects will prevent your form from destructing, so you'll have to .NULL. out the array in the QueryUnload() and/or Release() before the form will be able to close.
