Question : Adding and removing series for an Excel graph using VBA

Hi,
I am having difficulty adding a series to a graph that I have generated using VBA. I want to show different series depending on the value of a number in an Excel cell. This part of the code works well; however, when I try to add additional series to the graph so that I can show 3 different ones at once (while color coding the series points) I am not having any luck - I keep getting an error regardless of any syntax that I use.

I know that this is pretty simple and has to do with getting the syntax correct but I can't seem to figure out what it is.

As I stated, I want to be able to display one series (which will be different depending on the value of the cell) for 5 choices while on the 6th choice I want to be able t display 3 series in combination. If the user chooses option 1 -5 after choosing otion 6, the graph must only display one series again ( so I may have to remove the series after adding them - not sure).

Please examine the code attached.
