PHP Radio Buttion Verification

[primasilva]

Okay, I'm making a simple form for orders. Users input info, I make sure they entered everything I want, the way I want, and it emails the results to them and me.

Everything worked until I added in radio buttons. Having trouble at the verification stage.

I have

...the buttons in a form...

<input name="theName" type="radio" value="value1" checked/> Value 1
<input name="theName" type="radio" value="value2" checked/> Value 2
<input name="theName" type="radio" value="value3" checked/> Value 3

... then the verification bit...

if(document.form.theName.value!="value1")
{[do something]}

But it keeps doing the [do something] part.

I also tried if(document.form.theName.value.checked != "value1")

And I tried both ways with == instead of != and switching stuff around.

It's probably something really stupid that I'm missing...
