Hi, andrewsaad !!
Welcome to the cPlusPlus forum

Form1.h(145): error C2227: left of '->Text' must point to class/struct/union/generic type

This error causes when the variable (totalpayment) is missing (not defined) or wrong type (not one of these types : class/struct/union/generic) (totalpayment or Text)

But, what is your compiler? And, can you give your full source class please?

When you post the code, please always use code format tags - the <> button on the right.

Hope all goes well.

Firstly always use code tags - the <> button on the right

The error says that the variable to the left of the -> must be a pointer. In your case:

double investment = Convert::ToDouble (Investment->Text);


Investment is not a pointer, more over it is only a double, not a class object, or a struct. So there is no member to point to.

The error is pretty clear.

You have multiple examples of the same error.


There must be some other object that has the info you want inside it. You will need to pass this object to your function.
