Need Help with Redstone Bundled Output

I am trying to create a basic program that loops forever and runs my quarry.

Its on Pastebin: http://pastebin.com/wbWVtAHt

It says "Quarry:4: Expected string, number".

I don't know what that means, I thought I just had to tell it the side, which is the back, and the number that stands for the color I want to toggle.

It is supposed to pulse pink 60 times, with a 2 second wait between pulses, then the same for grey, then 8 times for light blue.

You never defined back as a variable.

Solution:

Use it as a string or define it as a variable

rs.setBundledOutput("back",7)
or 
side = "back" 
rs.setBundledOutput(side,7)

You will have to change all of these conflicts
