Filtering text box content HELP!

Hi all,

I’ve made a file that reads my URL string and posts it on a text box named queryString and my URL parameter is posted on that text box.

Waht I need to do now is filter that information into 3 diferent boxes, ex:
// this is OK
URLparameter = ?var1=val1&var2=val2&var3=val3

// now I need to filter that info for these boxes below
value1 = val1
value2 = val2
value3 = val3

I’ve published what I’ve made so you guys can see http://yalp.com.br/clientes/sm/urlParam/index.html?var1=val1&var2=val2&var3=val3

There is also a copy of my ZIP file if that can help in any way.

Please Help!!!

Thanks for the attention, best regards!!!
