It says in the Help:Extensions page that Variables is enabled by default, and it seems to work great here:

That 10 above is the result of using &#123;{#vardefineecho:foo|10}}, but if I include that on any page in my wiki, it will come out as plain text, without the desired effect.

Should I need to do something else to get it to work in my wiki? Thanks in advance.
