Jeff,

To do what Cetin suggests you could try the following:

The first time they press OK, put someting like this in the code of the click event (actually, you should make it a form method and call it from the button's click)

WARNING - UNTESTED CODE

local loObject
for each loObject in thisform.Objects
  if upper(loObject.BaseClass) = 'TEXTBOX'
    loObject.Tag = tran(loObject.Value)
  endif
endfor

The second time they press OK, do the following

local loObject
for each loObject in thisform.Objects
  if upper(loObject.BaseClass) = 'TEXTBOX'
    if ! (loObject.Tag == tran(loObject.Value))
      * Raise the alarm!
      return .f.
    endif
  endif
endfor

Cheers,

Andrew
