[Zope] Help! All my <> are now ?

I've just been changing colours on a table on one of my pages in Zope and now all the code on my pages has ? instead of ?>, eg ?TABLE WIDTH=100%??TR? What have I done??? And more importantly, how can I fix it easily? TIA -- Jenny Campbell User Support - Applications Eastern Equities Limited Ph: 06-876 7943 Fax: 06-876 8811 ---------------------------------
