Using from type in template

[Davidinh]

Hello vbb world,

I try to use some type as radio, checked in vbb template (custom template)but something of the standard vbb code i don't understand

in my template

<input type="radio" name="name1" value="value1" default>radio1</input>
<input type="radio" name="name2" value="value2" >radio2</input>

the function of the from worked ok but the page error as
Object doesn't support this property or method

i have looked over some vbb template where they used radio and checked type
and i don't understand some code line as
<label for="bla_bla_bla"> and id="bla_bla_bla"

Can all of you can tell me a method or do a property for these type of from in the template

any suggestion, ideal, how-to will be appriciated

regard,
