This is because each subsequent "Find" you issue will try to find the next
occurrence of the text you're looking for. Since your code is:

on mouseUp
  find "eating" in fld "F1"
  select the foundChunk
end mouseUp

The second time around, it can't find anything and 'the foundChunk' is
empty. So when you try to do a 'select' with nothing in 'the foundChunk' you
get an error. Change your code to:

on mouseUp
  find "eating" in fld "F1"
  if the foundChunk is not empty then
    select the foundChunk
  end if
end mouseUp

and you won't have any problems...
