Ok so we are getting close, basically what this is doing now is finding the words inside a class then showing us them in an alert.
<td><div class="productitemcell">Champagne Weadding</div></td>
<td><div class="productitemcell">1 line custom</div></td>
var divArray = document.getElementsByClassName("productitemcell");
for (var i = 0; i<divArray.length; i++)
But this is obviously not the final result we are after.
We need to be able to find the words "1 line custom" in the background (so the user dosnt see this happening) then once these words are found display a link.
Let me know if this is making any sense to you.
