function hiddenlinks() { var displaystr = null; var stylestr = null;
for(n =1; n < 100; n++){ if(n <10) displaystr = 'hidden0' + n; else displaystr = 'hidden' + n; stylestr = document.getElementById(displaystr); if(stylestr != null) stylestr.style.display = "none"; else break; }}
function showhidden(num) { if (document.getElementById(num).style.display == "none") { document.getElementById(num).style.display = "block"; document.images["arrow" + num].src = "image/arrow-closed.gif"; } else { document.getElementById(num).style.display = "none"; document.images["arrow"+num].src = "image/arrow-open.gif"; }}
