Problem with radio button value

Hello,
I have a problem about the radio button value, In fact, when I create my form, with radio button option, in property, choice, I fill "label and value" fields, but on my site, when I active the form, in my URL, I have just the label, and not the value.
Have you a solution?
Thanks.

Hello David,

Sorry, my first question was not clear.

I want to use a gravity form a way to show different pages. The user chooses the page title via radio button, he validates the form and he sees the correct page. So the form is only a radio button element, with the name of each page as label, and their post ID as value. I used a redirection option, in order to have the form redirecting to the correct page: http://www.votrepiscine.fr?p={Piscine:1}

Unfortunaletly, the merge tag {Piscine:1} only takes the label of the radio button, not the value, thus I get redirected to this url:
"http://www.votrepiscine.fr/?p=Hors+sol"

instead of this one:
"http://www.votrepiscine.fr/?p=1289"

Is this a bit more clear or do you need other explanations ?
Cheers,

Thanks for your answer Rob :) The form works now.
