Boolean branching using ASCII

[regcurry]

Could not find this in a search, which surprises me.  Is the following not possible in Mathcad 15?

Thanks for any help.  I can make it work if I use mathematical tests, But, I like to learn new things.

Which error message do you get?

Pls attach your worksheet as its hard to debug just a picture!

As far as i can see the if is on the right hand side of the assignment for Kpuj, but the otherwise is NOT!
So you would need to type the "Kpuj <---" on the line containing the "otherwise" as well.

Your value THICKTAMP is undefined.

You used a Boolean equals (bold =  instead of assignment  :=  ) in your attempt to give it the value "y".

Success!
