Error with shampoo.test()

[fishfishson]

I run shampoo.test() and get an error. Could someone help me fix this problem?
It says TypeError: 'float' object cannot be interpreted as an index

Try updating shampoo and let me know if it works, I've just implemented a fix.

It works. Only leave some warnings.
Thank you.
