There was a typo on the web page.

It should be "Firm, Retail Store" instead of "Firm, Retail" on http://www.capitalismlab.com/script---locks.html

The typo has been fixed.

And the Lock script only supports firm types (e.g. farm, retail store) and does not support specific retail store types (e.g. super market, convenience store)

[LOCKS]
Firm, Retail 
Firm, Supermarket

[LOCKS]
Firm, Factory

I tried to disable all retail for player in my script, but cant make it to work.

I put this in script file:

[code][LOCKS]
Firm, Retail
Firm, Supermarket[/code]

but retail building are all enabled anyway.

Then i tested:

[code][LOCKS]
Firm, Factory[/code]

and this works, all factory buildings are disabled.
