compile error: method or data member not found

[sorne786]

Hello! I need help with my code. Whenever I run the program, it would always say "Compile Error: Method or data member not found". It would always highlight the Private Sub part. What do you think is the problem?

Private Sub cmdResult_Click()
DIm a, b, c as Integer
a = txtNum1.Text
b = txtNum2.Text
c = a+b
MsgBox c, vbInformation + vbOKOnly, "Result"

What is:
txtNum1

Is this a activex texbox on the active sheet?

What is:
txtNum1

Is this a activex texbox on the active sheet?

txtNum1 is Value 1 in my code, and no its not an active textbox.

Not sure I understand.

Then I would think:
it should be:
c=1+2
