Hello, I am using Zope sine last couple of months. I have been using zope from source version Zope-2.1.6-src. My operating system is Turbolinux6.0 and my database is MySql. I have to make an search on a column having multiple selection i.e take for example I have a column for city in one of my tables which also contains many other columns. Now i make a search on multiple city along with the state in which that city belongs. The search is working fine I get all the data i want, But my problem is that i wan to display only 10 rows on the page.For this i am using batch processing. But it is giving me errors Such as key error [city],[state] and gives the url of my page where i m using batchprocessing. Can someone help me out how to overcome the problem this problem as this is very urgent for me. I think the varibles are not geting passed again when i click on next sequence. Thanx in anticipation of a reply and warm regards to all. Hope I am able to explain what my probelm is ? Vikas Mahajan
