[htmltmpl] Re: Templates with template loops within templates

[Eric F. <er...@dm...>]

Hi,

I just thought this might be worth posting. This is the template that is in 
the DB that is loaded
as a template var in the main page. The line:

<img src="<TMPL_VAR NAME=URL_BASE>images/shipping/<TMPL_VAR NAME=S_ICON>

is where the problem comes up. Every other URL_BASE in here is replaced 
correctly and of course all of the loop vars are fine as well.

Thanks,

Eric
