Struggling to open a received workflow

Hi everyone,

I’m a total beginner to Knime. I’m hoping someone can help me out with what must be an extremely simple problem that I’ve just been completely unable to figure out.

My colleague has e-mailed me a workflow to do some work with, but I simply cannot get it to open in Knime so that I can work on it. I’ve got the relevant Excel data sheet and I’ve gotten that as a node into the workflow editor, but I don’t know how to load all my colleague’s work into it.

I’m sorry this is a very basic problem, but I’ve been trying to read all sorts of other help posts and guides but I’ve still not worked it out! I’m usually not so technologically illiterate but I must confess Knime has me a bit out of my depth so if anyone can explain this to me like I’m a 5 year old I’d be immensely grateful!
