html tags and python

Yeah I also like just to be able to write in numbers.
That is how it works right now.

But then I will have to make some code, that validates if the day number is 
higher than allowed.
Like if it is January, the days arnt allowed to be higher than 31.

Will one be so kind and explain how I write that code:
Right now, the user has to put the data into a form:

print '''<form action='insertevent.py'><br>
        <p>Title :<br> <INPUT type="text" NAME="title">
        <p>Month (1-12):<br> <INPUT type="text" NAME="month">
        <p>Day (1-31):<br> <INPUT type="text" NAME="day">
        <p>Start (00.00):<br> <INPUT type="text" NAME="start"></p>
        <p>End (00.00):<br> <INPUT type="text" NAME="eventend"></p>'''

print '''<p><input type=submit value='Submit'></p></form>'''
print '''</body> </html>'''

Then it runs the insertevent.py script, which puts the data into my 
database.(Using postgresql)

form = cgi.FieldStorage()
title = form["title"].value
month = form["month"].value
day = form["day"].value
start= form["start"].value
eventend = form["eventend"].value

insert_command = "INSERT INTO events1(title, maanedid, dage1id,  start, 
eventend) VALUES('%s', '%s', '%s', '%s' , '%s')" %(title, month, day, start, 

insert_command2 = "SELECT events1.eventsid FROM events1 WHERE events1.title 
= '%s' AND events1.maanedid = '%s' AND events1.dage1id = '%s' AND 
events1.eventstart = '%s' AND events1.eventend = '%s'" %(title, month, day, 
eventstart, eventend)
res = cur.fetchall()
new_idevents = res[0][0]

insert_command3 = " INSERT INTO evr1 (eventsid, maanedid, dage1id) VALUES 
( '%s', '%s', '%s')" %(new_idevents, month, day)

print "<br>Arrangemenetet er nu oprettet."
print "</form></body> </html>"

Im which scritp, and how do I make an error message if the day is out of 

It is prolly something like:

if month = 1
    then days have to be >1 and < 32
else print " day entered out of range"
if month = 2
and so on...

Thanks for all your help, somehow it just makes more sense when I see it, I 
am still new to the whole code thing :)
