I have a page which contains 2 Contour forms (in tabs). I have added both of these to the masterpage using the Insert macro. When this gets rendered, the outer div for both ofrms have the same id

<div id='contour'>

Can you let me know if it is ok to go into the RenderForm.ascx and remove this, i am worried about unknown consequences. Also moving forward i would be interested to know to what extent this file can be edited.

Thanks
