Default in content block being substituted

[crb11]

I have the following in my template:

{content block="header image" default="{swfobject swf='uploads/header.swf' width='736' height='164'}"}

However, when I create a page with this template, the default has changed to

<p>$_tmp1</p>

(and this is also what is displayed).

A more standard default works fine. What am I doing wrong?

Thanks,

Colin

As far as I know the "default" parameter can only contain plain text, not a Smarty tag...

ps. is this what you are looking for?

Ah. I think that's true, but didn't realise what I had was a smarty tag. (I'm relatively new to CMSMS, having inherited a site and trying to tidy it up a bit.)
