VBA code stopping in odd places

Clear DayI have some VBA code that is stopping in unexpected places, almost as if a break point had been established on the line -- although there is no breakpoint on the line. The VBA error box comes up, giving the option to Continue/Debug, etc., and I can either continue or debug and step/run through the code, although it may break at another point in the code, or at the same place as it loops through the thousand or so iterations the code performs.

Any thoughts?

Thanks --
