insert userform, and then add a label, textbox,listbox ,and commanbutton into your userform.
just like this picture below:
you can change the name of your label and button by simply go to caption and edit.
double click your command button and type this following code:
Private Sub CommandButton1_Click()
Dim x, y, n, i, sum As Integer
n = TextBox1.Text
xValue = 0
yValue = 1
For i = 1 To n
xValue = yValue
yValue = sum
sum = xValue + yValue
ListBox1.AddItem sum
Next i
End Sub
Run your Program, lets assume that the user will input a value of 10.
click the button and the fibo series of 10 will save on the listbox just like example below:
Hope this will help... :-)
