JS Header: "-No Signature-" ECL Issue

http://www-10.lotus.com/ldd/nd6forum.nsf/55c38d716d632d9b8525689b005ba1c0/3b490e2889632ff685256ff600617ed0?OpenDocument

Further to the above linked post, which relates to an ECL issue with -No Signatue-, I have the same problem on a subform. 4 design elements in the form are set to run web\javascript but the values for the script are unpopulated. I would like to remove or deactivate the elements in the form. They are namely: JS Header, OnHelp, OnLoad, OnUnload.

Can anyone indicate how I can eliminate these unused javascript elements please?

Thanks for you help.
