You are correct with respect to my weakness on DOM manipulation, however my application is completed and running. The changing of the Day drop down box to reflect the correct number of days when the month changes is an enhancement I want to add. Bruce

Sorry, I don't understand what you mean by "Not a help desk." I have always assumed that these newsgroups were just that, a help desk for where highly skilled programmers can assist lesser skilled programmers.

Using these Nine select boxes, it's very easy for the customer to select his/her date, start time and end time, then clicking submit. No fumbling with the keyboard where typing mistakes can be made. I don't have to validate the date format. Did he enter 5/4/10, 5/4/2010, 4 May 2010, May 4, 2010, et. al. > > > My validation is done on the Server using AJAX. > > And when that fails?

On the client side, I can check for input mistakes, like the End date is before the start date. On the server side, I have to check is someone else has already reserved this time. > > The technical solution to what you are asking is not all that hard. Okay.

This should be an expected and understood norm for usenet postings. The bit I was commenting on was the TAGGED address portion, and NOT the domain name. Would you prefer I used a real, deliverable domain with the fred+usenet@ part, just to make a point? Didn't think so!

You see, a helpdesk is [usually] a paid position that has an certain obligations. Except for a rare few who have volunteered for special obligations, nobody here needs do anything. Your phrase: > Okay, you have made this into a fantastic discussion, BUT, the > solution as I request, is what I want. Strongly suggests that you have come in expecting answers. And if you paid a help desk, that might be a reasonable thing to expect. However, you have come into a usenet discussion group, and a discussion is what you got. Sometimes the answers you want come out of that discussion, sometimes they don't.
