[eventual]

Hi,
Looking at the script below, how do I write a range of 10 to 80 as a regular 
expression. 
I tried [10 - 80] but it wont work.
Thanks
##### script ##############
 
#!/usr/bin/perl

my $player_total_points = 70;
if ( $player_total_points =~/^(10..80)$/ ){
    print "yes";
}else{
    print "no";
}
