Invalid 'for' loop control variable 

You created a For...Next loop that has the same control variable as a loop it is nested inside. Alternately, you may have created a For...Next loop with an illegal control variable. The following demonstrates the correct structure of a For...Next loop.

      For counter = start To end [Step step]

    [statements]

    [Exit For]

    [statements]

Next

To correct this error

• Rename the control variable in your For...Next loop to something unique within the scope of the outermost loop.
