Hi I have an application that is working fine on a 6.02 server, accessed by a browser. However, the replica on an upgraded 6.5 server can’t display/open some forms. No particular errors beyond an indication that computed lookups are failing. The lookup fileds are on a subform that is present in other forms that open fine. And, as I say at the start of this post, it all works fine on the 6.02 server. Any ideas?
