I'm getting this error in .Net

"Specified argument was out of the range of valid values. Parameter name: index"

Then it point s to this:

Line 186: Dim tb As TextBox
Line 187:
<B>Line 188: tb = CType(e.Item.Cells(1).Controls(1), TextBox)</B>
Line 189: Addr = tb.Text
Line 190:

I just want to know which part of that bold statement I should be paying attention to with regards to the INDEX error. I'm VERY new to .Net and I haven't got the hang of debugging yet. Thanks as always!
