[AccessD] Roll Your Own Combo Box

Hey All
A while ago I developed a set of combo boxes for a client using list 
boxes, basically because I did'n't like the way the combo boxes were 
displaying on a form replicating their paper form. Anyway I have taken 
the idea a step forward using conditional formatting and continuous 
forms. The code is simple (no rocket science involved), there is no 
error checking and it is not 100% bullet proofed. Anyone interested in 
the demo, EMail me offline. 2 examples a single and a mutlicolumn combo 
box. Maybe someone will have some suggestions on how I can improve the 
multi-column combo box.
