in vintage basic language I am receiving a error when compiling. It is a calculator application I which the user selects an operation to be performed. When selecting an operation, a recurring error of invalid is appearing.

Invalid choice. Please try again.

Additionally, I believe the computation functions such as addition, subtraction, multiplaticon need to be altered because when entered 2 3, it outputs 23 and not 5 for addition, not 6 for multiplication.

code through replit basic
