I need to change something in the [login to view URL] page, only on this page these changes should take effect and I don't want conflicts on other pages so only bid if you know exactly what you are doing. Check the 2 images and the code I currently have in the [login to view URL] file: website: [login to view URL] Advertisements image 1. how it is currently image 2. how I want it to be state that you read and understand the project when you bid so that I know you read and understand it.
