Hello I got a problem where i think i have tried every batch-sequence variable, but can't get this to work. I have a database with two tables. Table1 contains searchterms and image names (only for images that are linked to a searchterm). Table2 contains the names of _all_ images (many images are not referenced to by a search term), their date and pagenumber. (The images are scans from historical publications). In a search screen i can search for terms, which yields a result screen. The results link to a display screen, with the image name as parameter (in the dtml-var 'im'). The display method uses a ZSQL Query with the following: params: im="" date="" select imagename, directory, date, page from table2 where imagename like <dtml-sqlvar im type=string> <dtml-if date> OR date = { ts '<dtml-var "_.DateTime(date)" fmt=ISO>'} </dtml-if> order by date, page I can use the following listing, using batches of 1, which gives me all images for the appropriate day, starting with the first image of that day. <dtml-in expr="Query(im=im)"> <dtml-in expr="Query(date=(_.str(date)))" size=1 start=qs> <dtml-in expr="Query(date=(_.str(date)))" next size=1 start=qs> <a href="<dtml-var URL><dtml-var sequence-query >qs=<dtml-var next-sequence-start-number>"> Next image<br> </a> </dtml-in> <img src="<dtml-var imagename>.gif"> </dtml-in> </dtml-in> The 'Next' section gives me the opportunity to page through the pages of the day (a Previous section is also planned). However, I want to start viewing at the exact image that was referenced to from the search screen. So what i want to do, is to set some sort of index and start viewing from there with the possibility to page to other pages for that day. In other words: The query already detects that image n6c117 is from date 02/02/1796. <dtml-var count-date> even gives the correct number of images for that day, let's say the count for date 02/02/1796 is 11 images: n6c111 through n6c121. Basically i have two questions, i think: How can i calculate the 'index' number of image n6c117 (that is: 7 from 11) How can i set that index in the lines <dtml-in expr="Query(date=(_.str(date)))" size=1 start=qs> <dtml-in expr="Query(date=(_.str(date)))" next size=1 start=qs> Things like 'start=im' etc don't seem to work here. NB: A further complication (syntaxwise) is the fact that in Table1 image names are spelled in uppercast, eg: N6C111, in table2 in undercast, as n6c111, so sometimes you might have to use constructs like (_.string.lower(imagename)). The date=(_.str(date))) construction is for similar reasons. Thanks and cheers
