I am trying to use the SpellBound class on a form to spell check the contents of an edit box. I have a button with the following:

LOCAL oSpellIt
SET CLASSLIB TO spellbound ADDITIVE
oSpellIt = CREATEOBJECT('spellit')
oSpellIt.CheckSource = 'thisform.edtComments.Value'
oSpellIt.DoCheck()

RELEASE oSpellIt

When I run the form and click the button I get the following error message:

'Object is not contained in a form'

Can someone please tell me what I am doing wrong!

Thanks in advance,
Russell
