I’m trying to pass the modified “text\_color” variable by dong:

def page\_text(type, source = @title)  
text\_color = type + “\_blue\_text”  
@title.text\_color  
end

With that, I’m getting an undefined method for “text\_color”.

How would you do that correctly?

nevermind, just solved it 🙂

def page\_text(type, source = @title)  
text\_color = type + “\_blue\_text”  
source.send(text\_color)  
end
