Microsoft Visual basics runtime error "6"-Overflow

Question

I am using Microsoft visual basics 6.0 on windows 8.1. And I have created a form for addition and subtraction. I am a school student, and due to lockdown, I can also not ask my doubt from the teacher. So, I am posting this question here and hope it is cleared faster as my IT examinations are close. In fact, this Monday only. When I try this form, it shows an error like this if I enter more than five numbers. 

Please help me with this its urgent!!!! Let me also share you my code: -

Private Sub Command1_Click()

Dim num1, num2 As Integer

num1 = Val(Text1.Text)

num2 = Val(Text2.Text)

um = (num1 + num2)

Text3.Text = um

End Sub

Private Sub Command2_Click()

Dim num1, num2 As Integer

num1 = Val(Text1.Text)

num2 = Val(Text2.Text)

difference = (num1 - num2)

Text3.Text = difference

End Sub

Private Sub Command3_Click()

End

End Sub

I am also sharing my form: -

Hello,

Thank you for reaching out. I am Harun an Independent Advisor and Microsoft User. I will gladly help you out.

I might have become a bit rusty on this yet I would recommend to define

um and difference as integer or Long before I assign the main value to them and see what will come out.

Dim num1, num2, um As Integer

Dim num1, num2, difference As Integer

or

Dim um As Long

Dim difference As Long

Please feel free to ask for more Information and let me know if this helps.

Sincerely

Independent Advisor
