         if (dip)
            f_cpps(getObj('v'+parseInt(d)));

I have edited the calander prep function with some help, it is now greyed out but is still selectable, any ideas? Thanks

unction prepcalendar(hd,cm,cy) {
now=new Date();
sd=now.getDate();
td=new Date();
td.setDate(1);
td.setFullYear(cy);
td.setMonth(cm);
cd=td.getDay();
getObj('mns').innerHTML=mn[cm]+ ' ' + cy;
marr=((cy%4)==0)?mnl:mnn;
for(var d=1;d<=42;d++) {
	f_cps(getObj('v'+parseInt(d)));
	if ((d >= (cd -(-1))) && (d<=cd-(-marr[cm]))) {
		dip=((d-cd < sd)&&(cm==sccm)&&(cy==sccy));
		htd=((hd!='')&&(d-cd==hd));
		if (d%7==1)
			f_cpps(getObj('v'+parseInt(d)));
		else if (htd)
			f_hds(getObj('v'+parseInt(d)));
		else
			f_cps(getObj('v'+parseInt(d)));

		getObj('v'+parseInt(d)).onmouseover=(dip)?null:cs_over;
		getObj('v'+parseInt(d)).onmouseout=(dip)?null:cs_out;
		getObj('v'+parseInt(d)).onclick=(dip)?null:cs_click;

		getObj('v'+parseInt(d)).innerHTML=d-cd;
		calvalarr[d]=''+(d-cd)+'/'+(cm-(-1))+'/'+cy;
	}
	else {
		getObj('v'+d).innerHTML=' ';
		getObj('v'+parseInt(d)).onmouseover=null;
		getObj('v'+parseInt(d)).onmouseout=null;
		getObj('v'+parseInt(d)).style.cursor='default';
		}
}
}

- this is the new prep
