javascript woes: select radio button when textbox is clicked

m trying to select a radio button when the text box next to it is clicked (when text is entered) I’m having trouble reading this code dreamweaver put in, heres the javascript code:

function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf(“?”))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
}

function MM_changeProp(objName,x,theProp,theValue) { //v6.0
var obj = MM_findObj(objName);
if (obj && (theProp.indexOf(“style.”)==-1 || obj.style)){
if (theValue == true || theValue == false){
eval(‘obj.’ + theProp + ‘= ‘ + theValue);}
else{
eval(“obj.”+theProp+”='”+theValue+”‘”);}
}
}

heres the text box tag that calls it:

<input name=”OTHER1″ type=”text” onClick=”MM_changeProp(‘9′,”,’checked’,”,’INPUT/RADIO’)” value=”OTHER” size=”50″ maxlength=”50″>

can anyone help?
