   Try getting 'the target'. I haven't used that much, so I don't know if
it'll work like you want it to. Or, have two scripts in each field:

on mouseEnter
  global theField
  put the short name of me into theField
  --or
  --put "<field name>" into theField  --where <field name> is the name of
  --each field.
end mouseEnter

on mouseLeave
  global theField
  put empty into theField
end mouseLeave

   Then have a script in the background layer:

on mouseDown
  global theField
  --do whatever with theField
end mouseDown
