You need to put quotes around IDs. I am assuming you have a form with
the ID frmAddVisitCal, and an input called "AP_DATE".

To get the AP_DATE input element, you would write:

document.getEle mentById("AP_DA TE");

But, you are putting that Javascript in ASP code (Not supported on this
group). You will need to write a string like this:

"document.getEl ementById(\"AP_ DATE\");"

Of course, that assumes that you escape quotes with a backslash. If I
remember correctly, VBScript with ASP uses a different syntax, but I
havent done that in years.

Next problem... using the javascript: method. See the FAQ:

You should probably use a different method... but without seeing the
code you are actually working with, I cannot suggest any more.
