InfoPath Dev

I currently have an info path form published via WSS 2.0 that has data validation on a number of fields. Some of these fields are rich text boxes that are set as cannot be blank by using the expression "field name" is equal to not(.//node()). What I am trying to do is have a button in the form that clears the contents of the fields. So far I have managed to assign a rule to set the field to blank, however where I am struggling is that the form can then be submitted with the blank field because it seems that the data validation is not reset. Can anyone help me please? Thanks

Instead of data validation, try conditional formatting. You can make the submit button inactive until the field is filled out. Then you can make the submit button inactive when the user clicks the button to set the field to blank.

I want to know that how you are assigning vales to blank? becasue while assigning the values to blank through rules you must be using like " ".

That is wrong way. You should use it like "". Then it will treat your rich text control as blank.
