Using a button to add 1 to a counter....

Haven't used vb in years so sorry for the rustyness here.
I'm using a form to display excel data. I'm taking multiple fields across one row and displaying them in textboxes. When I reference the cells I want to use a counter to replace the row index as in..
textbox1.text = cells(counter, 1)

I then need a button that will add 1 to that counter so it will essentially take me to the next record. Any help will be greatly appreciated....

under the button to move to next row

VB Code:

if clng(txtBox.Text)+1 <65535 then
    txtBox.text = clng(txtBox.Text)+1
end if

txtBox is the textbox controls name...
