[Zope] Problems with dtml-in batch variables.

Greetings, I am using the ever-so-handy next-sequence-* and previous-sequence-* variables for a batched list. This all seems to work fine, allowing users to look through bite-sized portions of the list. However, there seems to be a problem. Whatever calculates these values appears to assume that the numbers are sequential, which, in my case, they are not. So, whilst i get the correct number of items each time, they overlap when they shouldn't, and the next/previous limits are reported incorrectly. The dtml-in tag in question is : <dtml-in "sqlQueryHere()" size=4 start=qs orphan=0> Any comments? -- Have a better one, Curtis. <dtml-var standard_work_disclaimer>
