What on earth is NewLine? Is it a global array of some sort? Since the combos both use fields from the same table as their RowSources,why not set the BoundColumn of the first column to 2 and set the BoundColumn of the second combo to 1. Then, in the valid of either combo, all you have to do is set the value of the other equal to this.value.

Of course, I have no idea what on earth the controlSources of these combos are meant to be doing ;-)
