if(document.getElementById('target-b')){
  document.getElementById('target-b').getElementsByTagName('td')[2].firstChild.nodeValue
= 'Email';
} else if(document.getElementById('target-x')){
  document.getElementById('target-x').getElementsByTagName('td')[2].firstChild.nodeValue
= 'Email';
}

if statements always need a condition

if(something){

} else {

}
