This template is the single source for all Hardness values. It is meant to be the single source for this information; this way, when new blocks are added or values are changed, they can be changed here and automatically propagate everywhere they are used.
If you got here by following a "?" link, it means the value for this parameter is not defined. There are two main reasons this could happen:
The page's name was changed, but it hasn't been updated in this template yet. Edit the module and fix the name.
There is a new block, and data hasn't been entered for it yet. If you know the correct value, edit the template and and add a new entry. Please don't guess or put in something random just to make the "?" go away!
