Remove id sign from scrollDown parameter string
- Since scrollDown uses getElementByID, the program already knows that the parameter is a string as the id
- id sign is therefore, unecessary, and was causing an error where the box was not scrolling due to unknown element referenced
- Error is fixed. Scrolling in chatEntries div is working.
