Load list box

[h_aesa1]

I have this piece of code that loads a list box and it has worked without 1 problem for the longest time.

Today, there have been 4 or 5 instances when it doesn't work, where I hit the load button and it does nothing.

I have closed down and restarted and it seems to work but this is very annoying....can someone please give advice or explanation as to why this is happening

below is the code I have

thanks
