woocommerce pricing issue

Good afternoon.

I have woocommerce and canvas.

I have products that have a minimum order of 100 units.

The product is
2.43 each at 100 -299 Units
2.12 each at 300-500 Units

Etc.

The pricing should read starting at $1.54 ( the 10000 piece price )

I have a bunch rules and plug ins and php hacks. Now the site doesn’t work and none of the plugins either.

Reloading function.pho and starting over on building the products.

Any help with these three problems would be appreciated.
