    Not sure how to approach this problem

    I recently got some very useful and precise help from these forums...that worked well. So I figured I'd cast my line out here first. I do not know the best way or rather most effecient way to go about an issue that I have come across. It relates to the help that I recently got but here is the basis.

    I have a table that has this information

    Date | Name | Start_Time | Event




    There are a bunch of queries that i've had to set up, and there is one that I do not know if it is even possible or what I will have to do to get it to work. But it goes something like this. I need the next Start_Time for the direct chronologically next event, in a seperate Column with no Date carryover, and no person carryover. So at each change in Date and/or Name, do not record the next start_time.

    Date | Name | Start_Time | Next_Start_Time | Event

    you have to use recordsets in code. you can't do it otherwise (if I'm reading this right).

    you can't perform vertical manipulations in queries through the interface alone.

    Seeing as though you want the time of the very next next event associated with the current one, I asume there is a correlation between Start_Time and Next_Start_Time. Is this calculable? For example, will event n always start x time after event n-1? If so, you don't even need to store it. Just calculate it on the fly.

Please reply to this thread with any new information or opinions.
