Trouble Flattening EDI data

Hi

I am having trouble flattening EDI data.

MEA+WT+AAD+KGM:476.9'
MEA+CT+SQ+NMB:8'

The 2 mea records at the bottom need to go to different fields in the same

record.  I use 2 equal functoids to determine if they are AAD or SQ, and 2

Value Mapping (Flattening) functoids to put them into different fields,
but 
they always produce 2 records. In looking at the do***entation an another 
post in .General  "Help on Looping and Value Mapping functoid".  This
should 
work.  But I am getting 2 records.

DIDGBB                 911112    ACW0496      8     AB 

Is this the correct way to go about this?  What could I be doing wrong.

TIA
