Declaring the variable in Home eliminates the syntax error, but setting it equal to some number results in a constant plot ... For example X = 0, results in 1/2 * x^2 always = 0 ... no parabolic curve.

Too bad the app doesn't allow you to easily swap out a variable when bringing an equation over from CAS.

I guess you just have to modify the equation for the app.

I don't have access to the calculator now, indeed it is strange.
But when you use the uppercase X , check the actual value of it.
Global predefined variables also have zero as contents.


Edit:
Peraphs there is a way:
Try to use uppercase variable X in CAS to see if it woks.
