Hi,
So, another idiot (probably) question:
I'm trying to figure out Google Analytics. The very helpful instructions say insert the code into the <head> section.
My Web Designer User Manual says:

Adding code to page head
Some code needs to be inserted into the head (<head> tag) section of the exported
HTML code, instead of to the body (<body> tag) section as it is by default.
To do this, click the HTML code (head) button in the Placeholder, Website or Page tab
of the Web Properties dialog and type in or paste your code.

That's great... Easy to understand, but...
I can't find the HTML (head) button anywhere on any of the Web Properties dialogue tabs.

Where do I find it? Or, where exactly do I put the Google Analytics code?

Many thanks,
Sara
