Solution 1

In the Click event of Button3, the statements

VB

Label1.Text = comboresult
tmr = Label1.Text

make comboresult equal to tmr. So, after pressing the forward button, when the backward button is pressed, the following if condition in the Click event of Button2 will be true

VB

If comboresult = tmr Then
    Exit For
End If

hence, the backward logic may not be working after pressing the forward button.

That leaves me in the same place as now..is there not a attribute to the combobox object that will allow me to set a variable to the value of either the previous or next value in the combobox based on the currently selected value of the combobox...sorry for being such a newb.
