    i've tried /(\W)*(\d)*(\s){2,}/ but because of the \W it ignores the \s{2,}. What i need is something that will allow only one space.

          What i need is something that will allow only one space.

      From perldoc perlre: 

                 {n}    Match exactly n times 
           {n,}   Match at least n times
           {n,m}  Match at least n but not more than m times
      If you want to match exactly one space you could either use just \s or \s{1}.
