Regular expression does not execute runtime

Question

Hello adobe collegue's,
I am currently stumbling on a strange issue regarding javascript embedded to compress a string:
// main function to compress any string, removing all non-word characters and making the string all lowercase
function compressString(input){
    var patt=new RegExp("\\W","g");
    patt.compile(patt);
    var output = input.toLowerCase().replace(patt,"")+"YESS";
    return output;
Somehow this code does execute perfectly while previewing in adobe designer 9.0.0.2 but runtime all javascript does execute except for the part mentioned above.
I know this part is executed because in the result i see the string "YESS" added to the response of this function.
Somehow the pattern is not compiled, or executed runtime...
I also tried more simple regular expressions but none of them actually worked.
For the templates the option client is set where to execute the javascript, although while testing the options to solve the issue is also tried settings both and server. None provided the solution.
Can someone provide any help...it's appreciated!
Thanks,
Marcel

Hi,
you can make your function more simple.
function compressString(input){
          return input.toLowerCase().replace(/\W/g,"") + "YESS";
