Something like this, not tested, and you may have to tweak it.

local lcDummy
for x=1 to 20
  lcDummy='yourform.text'+trans(x)+'.value'
  if empty(eval(lcDummy))
    messagebox(yuststem(lcDummy)+' is empty')
  endif
next

NB! I am not debuggung this for you, I only want to help you in the right direction.
