In Sharepoint designer I am trying to set a custom display form for a list, following the instructions in the Sharepoint designer help.
I've got a functional display form, called DispForm3.aspx. I know it works since I tested it by replacing the form name in the normal URL where a display form is opened.
However I can not get the list to accept this new form as the display item form.
In Sharepoint Designer, in the List Properties Supporting Files tab I set the Display item form to be DispForm3.aspx and press OK. When I look again I see that the Display item for is DispForm.aspx.
This happens on any list that I try to customise the display form for, even new ones.
Sharepoint designer is allowing me to set the display item form to DispForm3.aspx but is not saving it, or is failing silently when it tries to save it.
Any assistance appreciated.
