Can I pass multiple variables through a list menu in Dreamweaver
I have a list menu that has the following choices
1-100
101-200
201-300
etc.,.....
In mySQL statement I need to get those 2 values in my BETWEEN var1
AND var2 condition.
Dreamweaver has the ability to pass a value through the selection, but how do I pass multiple values through the list menu? can I separate them through commas? Brackets?
Any help is appreciated.

probably obvious, but above code may have to be changed to use .php extension; I've got my system setup to interpret .htm with php so I forget about that sometimes.

If I am using these numbers in a mySQL statement will the values that are split end up as a string or a integer? If there a string my WHERE statement in mySQL would need something numeric to be able to carry out a =, or a <= or a BETWEEN - AND statement?
re: "will the values that are split end up as a string or a integer"?
Since php is what they call "loosely typed", I think you'll find that you'll be able to use the data as either number or text. eg. try the code below -- you can do a mathematical operation on var1 and var2 and then immediately do a string operation on them. When you add the variable to a database, I think the variable type will adjust to whatever the database column type is, i.e. integer, char, etc. If you find you have any problem with type mismatch, it is possible to force the type, eg. $var1 = (Integer)$var2, see this for more info: http://hudzilla.org/phpwiki/index.php?title=Forcing_a_type_with_type_casting

$value = $_POST['mydatarange'] ;
$value_split = split("-",$value);
$var1 = $value_split[0];
$var2 = $value_split[1];
$var3 = $var1 + $var2;
$var4 = $var1.$var2;
?>
<p><?php echo "Var 1 is: ".$var1; ?></p>
<p><?php echo "Var 2 is: ".$var2; ?></p>
<p><?php echo "Sum is: ".$var3; ?></p>
<p><?php echo "Concat is: ".$var4; ?></p>

Thanks for the follow up. Very clear explanation. I did get it to work perfectly. I'm just a newbie, but this is kinda like art. Give a person the canvas and the brush, and you can create just about anything! Brilliant
