Passing variables with $_Post

I have a page that is getting data from a previous page.  I want to pass the same data to a third page.

I've tried this on the 1st page:
<?php
$work = "?".
                        "Min_Store = ".$Min_Store." ".
                        "Max_Store = ".$Max_Store." ";
?>
<a href =  "Survey_Print.php
      <?php
            echo $work;
      ?>
">   
<br>
                
<input name= "Print" type="button" id="Print" value="<?= $Button_Value; ?>"

Then on the 3rd page, I have:

echo "Min = ";
echo $_GET['Min_Store'];
echo "<br>";
$Min_Store = $_GET['Min_Store'];
$Max_Store = $_GET['Max_Store'];

The URL on the 3rd page looks correct, however I'm not getting the data.
The echo on page 3 just says "Min = ".
What am  I missing.

The first thing is that there should not be any spaces in a URL, especially in a 'name' for a name/value pair.  Second is that all the values should be urlencoded to prevent them from 'breaking' the URL.  http://us3.php.net/manual/en/function.urlencode.php  Third, each 'name' after the first one needs to be prefixed with an '&' although '&amp;' is considered to be a better choice.

It should end up looking like this:

Survey_Print.php?Min_Store=Min_Store_value&amp;Max_Store=Max_Store_value

Or like this:

Survey_Print.php?Min_Store=123&amp;Max_Store=456

I changed the code to read:
$work = "?".
                        "Min_Store=".$Min_Store."&;".
                        "Max_Store=".$Max_Store;

The URL is displaying:

http://chris.mrbreeze.net/Survey_Print.php?Min_Store=2000&;Max_Store=3500

The echo is still returning "Min = "

I just tried something and it works.  I changed $_POST to $_GET.

What's up with this?

Min works with the $_GET but Max is returning blank.

Ok.
I duplicated the code from your previous post:
Survey_Print.php?Min_Store=123&amp;Max_Store=456

So get rid of that ";" after the "&amp".

No, you didn't.  Somehow you put an extra ';' in there.  It's either '&' or '&amp;' but Not '&;' and not '&amp;;'.
