heteroskedasticity test_variables"is not defined"??

[fdmyang]

Saying my greatly thanks in advance for this problem firstly.
I have spent almost the whole day to solve this problem but failed and have to come here seeking more support.

I have conducted the OLS test already and wanna continue for Heteroskedasticity test but whenever I make it the system have told that the variable "is not defined". I checked all the process but not find any problem. Is there anyone can tell me what's problem of this??

btw: i got some instruction as "view_reside test_heteroskedasticity" ,but i cannot find it under view of my table. So i just use: "quick_equation estimation", and the i keyed my variable and have been told it.

Thank you very much!
