    You need to use double quotes if you want to interpret the value of a variable. You can use this code to insert the $i variable value into $website:

    print "Content-type: text/html\n\n";
$i=1;
$website="url/$i?s=c";
print $website;
    Code (markup):

    A few issues your code has:

    1) You have an extra apostrophe after $i=1;' Having that ' will break your code.
    2) You are settings $websie variable, but printing $website variable. Those two are different (missing the t).
    3) You are placing the $i in quotes, which will translate it into string. If you want it to use a variable, remove the quotes: $websie='url/' . $i .' ?s=c';
    4) You have an extra space before the ?: $websie='url/' .'$i' .'?s=c';

    Overall I would say you are starting to learn Perl, in which case you should cover the basics of the language first. You can read this ebook to increase your expertise: http://www.perl.org/books/beginning-perl/ (or google learn perl).
