Please ensure there is something connected and compile "inside" and "outside" the block. Let us say for argument you have %MW100 connected to the In/Out.. Make sure that %MW100 is not used elsewhere. Also check that MB101.0 is not used elsewhere. Does this help? w

The trigger to the ADD does not have any edge triggering. So in actual fact the ADD should repeat for every scan.. strange that that is not the case. w
