The names you use in processing a <form> submission must match the names of the fields
in the <form> that was submitted!!!
<select name="SelectStudent" ...>
But then look here:
If Request("rsTraveler") = "1" Then
Then this statement makes no sense at all:
ElseIf (Request("alldates") = "") OR (Request("Start") = "" AND (Request("End")) = "" OR (Request("alldates") = "") Then
First of all, you are *REPEATING* the Request("alldates")
. And in a way so wrong I don't have time to explain it.
Secondly you are saying "if the user did not check 'alldates' *OR* if the user didn't input start and end dates, it's an error. So suppose the user does not check 'alldate'. And the user does put in start and end dates. You will *STILL* mark that as an error, because of the OR condition!!!
Your logic is completely backwards!
ElseIf Request("alldates") = "" AND ( Request("Start") = "" OR (Request("End")) = "" ) Then
