Stuck on System Inspection page-help!

[mac-chick]

I'm on an iMac G5, PPC, OS X 10.4.6. I've installed MAMP v. 1.6. I'm trying to install Zen-Cart v. 1.3.7. I'm at the System Inspection Results page, where the install button is at the bottom and I have the error: Current SQL Cache Folder= (then the path to the cache folder) --> Unwritable
I changed the permissions on the folder to me, group, others can read & write. How do I change the chmod to 777? In terminal? Is that the problem?
Thanks for any help!
