Getting signals to work

[jt233]

Hello, so I am still learning how to place signals and get them to work. I am trying to build a route and have a KHS 2 Aspect signal placed on a side track before joining the mainline but no matter what the signal show's red. I followed a few tutorials on youtube so that I could place them right but still won't work. Can anyone help me get the signal to work properly? Also, after taking the screenshot I added a junction signal further up the line and it is not working either and just shows red. I will include a screenshot so you can see what I am talking about

Here are some more screenshots to show how I have placed my signals. No matter how I switch the tracks the signals just show red.
