Have I represented dy/dt correctly?

[tremor65]

Hi, I have what I think is mostly a correct model but it is not giving me the results I'm looking for. I don't think I have represented y(t) correctly. The equation is as follows:

dy(t)/dt = 0.2((y(t-tau)/(1+y^10(t-tau)))-0.1y(t)

with y(0) = 1.5

The model is attached. It ends up giving a value of ten regardless of the step size which is not the correct answer. Any troubleshooting help would be appreciated!

Thanks!

I solved it for you.
You had 2 mistakes. I attached the file and I'm sure you can see the differences between what I did and how you did it.
Very close however.
I can answer any q's about it.
