I have a form that is spread over a number of pages. A field-forwarder is used to forward the selected entries from one page to the next, until the user submits the form. Now i would like to ask if is it possible to have a radio-button disabled, if another radio-button on a previous page is selected? Below is an example of what i have..


//==================================================
<FORM method="post" action="database.php" id="myform">

<INPUT TYPE="radio" NAME="material" VALUE="iron">Iron
<INPUT TYPE="radio" NAME="material" VALUE="wood">Wood
<INPUT TYPE="radio" NAME="material" VALUE="plastic">Plastic
<INPUT TYPE="radio" NAME="material" VALUE="glass">Glass

<INPUT TYPE="submit" id="submit" value="Proceed >>">
</FORM>


//Next page

<FORM method="post" action="database.php" id="myform">

<INPUT TYPE="radio" NAME="process" VALUE="injection_moulding">Injection Moulding
<INPUT TYPE="radio" NAME="process" VALUE="blow_moulding">Blow Moulding
<INPUT TYPE="radio" NAME="process" VALUE="drilling">Drilling
<INPUT TYPE="radio" NAME="process" VALUE="casting">Sand Casting

<INPUT TYPE="submit" id="submit" value="Proceed >>">
</FORM>

//===============================================================

Now what i want is this: If a user chooses "Plastic" from the first form, the next form would have only the first two values enabled (i.e. drilling and casting are DISABLED).

How can I do this?
