Test page. To create an iframe area, click on "edit" on the general page area, scroll down until you see the little insertion teardrop and its line, and then from menu that appears, insert "code" from the "More" group of insertion options. Insert the code and save. Then hover over top left corner of the page design to click on diagonal arrow at top left of page to throw the page into viewing mode to see what you've got.
Ring me anytime 0425 211313 to walk through anything. I'm usually at desk 10 am to 4.30 pm 7 days, although (unusually!) I am away from PC much of the day on 14 to 18 March, but will be able to answer emails and look at anything during evenings.
