  (this should be in the PHP section....)
  
  there are many ways, perhaps the best two are GET or POST variables (you could use a cookie but that would be silly in this case, for a number of reasons)
  
  the GET variable goes in the query string. look at the URL of this page and you'll see a question mark and other stuff at the end of the address. so if you want to pass a variable on, you could build up a hyperlink like this:
  
  <? $month = 12; ?>
  
  Click <a href="./page2.php?month=<?=$month?>">here</a> to view page two.
  
  
  
  and then on page two, to access the GET variable you do it like this:
  
  The month is <?=$_GET["month"]?>.
  
  
  if you want to use a POST variable, then set up a form and have a text box labelled "month", submit the form to "page2.php" and then access like this: The month is <?=$_POST["month"]?>.
  
  I hope that's clear, any questions just post back

  thank you very much! that seems to help me a lot.
  

  
  now i have a new inquiry.
  

  
  ---i created an array of textboxes:
  

  
  page1.php
  

  
  <form action="/page1.php" method="post">
  <?for ($x = 0; $x <=2; $x++)
  {
  ?>
        <input type = "text" name = "boxname[]">
  <?
  {
  ?>
  

  
  

  
  <input type="submit" />
  </form>
  

  
  

  
  --the question is, if i want to get the values of each text box, how can i?
  printr($POST['boxname']) as i know is used to print all the values, but it only want to read each the value to be used in updating the database individually according to the index.

  it puts it as an array, so construct a loop with a variable such as $x which will increment one each time, and put it in the square brackets
