Hello, I have tested my code in my editor and it passes, but when I try to run it here, I get the error 'multiply' is not defined'. Can someone help please?

whoops, forgot about that. many thanks for your help

thanks.

I am now getting the following message when I run the tests though:

expected 'true' to equal true....

?

My code passes in my own code editor with the right answers when I run it, but it is failing when I attempt it in codewars. Can anyone help please?
