Disable a radio button in Select Question

Question

I  have a similar question but in a Select type with radio buttons:
  In my question "Cat1" I have "Other Specify" in the 7th list member.
  The next question is "Cat2" where I have listed 8 members:
     1 to 6 will be always shown
     7th is the one specified in Cat1 in Others as [% Cat1_7_other %]
     8th Other Specify

What I need is that if other is specified in Cat1, 7th shows that value and 8th is not shown. I tried using the next code in Text Editor of the 7th option but is not working:

<script type="text/javascript">
    var Otro = "[% Cat1_7_other %]";
    if (Otro == ""){
        remove(Cat2List,7)
    } else {
        SetValue(Otro);
    }
</script>

For your question Cat2, instead of a predefined list just use a constructed list using Unverified Perl in the logic.  For this example, I will assume the name of the list is 'Cat2List' currently and that Cat1 and Cat2 are single response questions.  I am adding all 8 items of Cat2List.  Then adding item 7 if the answer at Cat1 was 7, otherwise adding item 8.  So the list will always have either item 7 or 8 but not both.  Hope this helps.

ADD (Cat2List)
Begin Unverified Perl
if(VALUE("Cat1")==7)
{ADD("Cat2List",7);}
else {ADD("Cat2List",8);}
End Unverified

It is not working, it always shows me Others. Not sure if this affects but Cat1 is Check box type, is it the same code?

Yes, that does make a difference, sorry I missed that.  I modifed the code below to only add the first 6 items always and then I modified the perl script for a checkbox type at Cat1.

ADD (Cat2List,1,6)
Begin Unverified Perl
if(VALUE("Cat1_7")==1)
{ADD("Cat2List",7);}
else {ADD("Cat2List",8);}
End Unverified
