Undefined operation: "false times 4em" about susy

I need more information than that. What are your settings? What is the value of $navspan?

[jadiaz]

looked more into it and found that rc2 sass/susy/_functions.scss is still using the older columns syntax.

confirmed when I changed

@include columns($navspan omega);

[mirisuzanne]

Nope. functions.scss doesn't have any mixins, only functions. If @include columns() is working for you, you need to gem uninstall compass-susy-plugin to get rid of the old Susy versions on your machine.

I'm encountering the same issue. I followed the steps to uninstall compass-susy-plugin, but there was no plugin to be found to uninstall.

Line 21 of _functions.scss: Undefined operation: "false times 2.86885".

This ended up being an error on my part. I had forgotten to declare $navspan in my _base.scss and so it was a math problem
