Tim thank you so much for this "easy to do" answer. I did get it to work and I went into the embed code and added an "s" to the http - that brought it up quicker - in IE I still get a query regarding "Only secure content is displayed" - I then have to click on Display Content to see the Sim and play the sim. I have closed Moodle and opened it and I still have to click Display Content. I added the "s" to only one http - I am missing something?
Again I do thank you for your help - Nancy K.
