Edit not allowed for a field in data input form?

[G Lam]

Hi,
I have a data input form with subform. I set the both forms to allow edit,
addition, deletion and input as for the forms to be a data input form. The
subform is a continuous form. How can I prevent only one field in the
subform from being edited by the user if the user clicks on that field.
While the user can click on other fields to do editing?
I tried the On click event for this field:
forms!mainform!subform.Form.EditsAllow = No
But it won't work.
Any idea?
Gary
