JavaScript Virtual Assistance (Debug)

Hello, I have two small JavaScript adjustments needed. English skills are important to ensure good communication between us. Obviously I need someone who is comfortable in JavaScript (Expert preferred) to complete two amendments to help me save time. 1. I need an existing dynamic link to be able to scroll to an anchor point (also dynamic), I have created a Stack Overflow question about this: [login to view URL] 2. Secondly, I need two items adjusted. They fade depending on the scroll of the user and I want to modify the opacity; when it fades and when it is 100% opaque We can complete this via TeamViewer or I can just send you the files, I will inbox you if your bid does not look like a copy & paste job
