Can someone help me in Mathcad Prime with the plot in the file attached

I am new to prime can someone help me with the plot in the file attached?

I've converted your Mathcad 12 file to Prime 8.

Prime supports a separate placeholder for your units, Instead of:

You should:

Then it plots.

Further down you define ng as a unit (10^-9 g). You should 'label' that unit as a unit.

Labels are similar to the type tags you know from Mathcad, but not the same. Prime tries to label all your input automatically. While that often goes right, it sometimes goes completely wrong.

Success!

I thought I had changed the labels from Mathcad 15, if  not thanks.   I am going to incorporate your suggestion, thanks

I have made the changes suggested I THINK.   I am interested (need help) in  first plot to work.  If I can do that perhaps I can figure out the rest.  Sorry I am slow, I started about a week ago

Please attach your Prime file.

Success!
