... print_r()/var_dump() $_POST["Ind[]"], what do you see? Nothing I bet. Why?
See manual > PHP and HTML for details.
Basically the contents of your form elements named 'Ind[]' have been placed in
an array named 'Ind' and lives inside $_POST, ie $_POST['Ind'], and you can
print_r() to see what it contains.

Yes, if you're using this method to pass them on:
searchresults.php?Ind...
Unfortunately, you can't just stick $_POST['Ind'] in there:
searchresults.php?Ind[]=$_POST['Ind']
There are 2 way you can do this:
a) Pass the individual elements of $_POST['Ind']
or
b) serialize() $_POST['Ind'], pass it as a single element, then on the
receiving page unserialize() it
Conceptually (a) will probably be easier to understand so:
you need to build a string which looks like:
Ind[1]=value1&Ind[2]=value2...&Ind[n]=valuen
which you append to your URL like so:
searchresults.php?Ind[1]=value1&Ind[2]=value2...&Ind[n]=valuen
This can be done using a foreach() on $_POST['Ind'], and implode(). Remember
to validate each item as you go along.
And PLEASE, stick:
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
on top of all your pages whilst you're developing.
