    Help with basic console application

    hello-

    I need a little help finishing a program for school - I missed class last week and am a little stuck with one of the request from the professor.

    I'm not sure about how to get the code to display invalid integer when you choose option 4 and you try to divide by 0 as of now it just displays nan = which i know is visual basic stating infinity. If you could point me in the right direction that would be great - as I want to get a + on this assignment.

    This is what i have so far.


    Thank You


    Code:
    Module Module1
    
        Sub Main()
            'Store needed Variables
            Dim num1, num2 As Integer
            Dim opt1, opt2, opt3, opt4 As String
            Dim choice As Integer
            'Prompt user for 2 Integers
            Console.WriteLine("Please enter 2 numbers?")
            num1 = Console.ReadLine
            Console.WriteLine("Please enter 2nd number")
            num2 = Console.ReadLine
            Console.WriteLine("Please Select a following option:")
            Console.WriteLine("Option 1 = Add both integers")
            Console.WriteLine("Option 2 = Subtract 2nd integer from 1st integer")
            Console.WriteLine("Option 3 = Multiply Integers")
            Console.WriteLine("Option 4 = Divide 1st integer by 2nd integer")
            Console.WriteLine("What is your Choice?")
            choice = Console.ReadLine
            opt1 = num1 + num2
            opt2 = num1 - num2
            opt3 = num1 * num2
            opt4 = num1 / num2
    
            If choice = "1" Then
                Console.WriteLine("Option 1=" & opt1)
            ElseIf choice = "2" Then
                Console.WriteLine("Option 2=" & opt2)
            ElseIf choice = "3" Then
                Console.WriteLine("Option 3=" & opt3)
            ElseIf choice = "4" Then
           Console.WriteLine("Option 4=" & opt4)
            ElseIf choice = "4" And num1 <= 0 Or num2 <= 0 Then
                Console.WriteLine("Error Invalid Integer")
            Else : Console.WriteLine("Invalid Choice")
    
    
            End If
    Kind of stuck at the last part.
