Hi Joel and thanks for your quick answer.
I'm using an Oracle database and I already have the program with Forms and it works pretty well, but I have no idea on how to do it with ASP. I was trying a few codes, but it didn't work because first thing is that the data I have is Varchar and I don't know what command to use to get to the next hour, for example: in Oracle the way I do it is just like this: If substr(schedule,1,2) between substr(schedule1,1,2) and substr(schedule1,3,4) then
message('You have a clash...please verify');
If you have some code that could help me, I will be very thankful because I'm not a pro with ASP yet, only Oracle and Forms.
Thanks a lot!!.
