Input from a text box into a url

[Noodle7]

Hi

I have a input text box and this input text must take the text entered into it and direct it to a URL. so if a person enters a 100 into the text box it must take them to www.help.org/100.htm , there will be alot of the pages
www.help.org/101.htm and www.help.org/102.htm etc ....

so I am looking to have a generic www.help.org/xxx.htm and have script that adds the number in the url www.help.org/100.htm ....therefor the script just added in the 100...

Hoping someone can help me with this one
Thanks
