Hi there, trying to ad adsencde to my site. I have code to paste, but really have no idea where the code should go. The tool tip says it needs to be pasted in between and tags… simply dont knmow where to look to find these. Can anyone help please?

On the editor menu select insert html frame, paste you code into the html frame. You will find videos showing you this process on youtube…

THank you Mike got it and done.
