Creating a rollable token problem

Hi All, I'm sure I'm doing something stupid but I can't figure out what i've done. I've created a rollable table with 3items, each item has an image.  I am trying to create a token for the rollable table.  I've clicked onthe token button but nothing seems t happen. Tha page I am trying to add it to is quite large and already has many tokens on it,  could it be a memory problem?  How can I find out. Thanks in advance guys Andy

It’s probably creating the token in the middle of the page and you’re losing it in the clutter. Try on a blank map page then copy and paste to the page you want it on. 

Knew it was something Stupid I was doing,  Thanks Andrew
