Custom Product Price

I am charging an additional price to the base price when adding custom images or text. This is working, but it is not reflecting this in the total on the product page. When I add the item it will show the price with the custom price.

I am also using an Addon plugin that has conditional logic for finishing of the product. When the addon is selected as yes the total from the custom product is voided. It will not add the custom price.

Example 1: The product is $220. Adding custom text adds $50, making it $270. When adding to the Cart it will show the correct price, but not on the product page.

Example 2: The product is $220. Adding custom text adds $50, making it $270. When the addon is selected, that is $27.50, the custom text is voided in the Cart. The price is only showing $220 + $27.50 = $247.50. The price should include the additional $50 from the custom text and the product should be $297.50.

This needs to be fixed please.
