Is there a way to exclude data in a list box?

[#1]

For example: 

Example List Box1
32578977
34562877
23125967
I need to look up last 2 digits for my exclusion and my exclusion criteria is 77
So the List Box should only show:
23125967

[#2 · Accepted solution]

for that make the list box use an expression:

if(right(yourfield,2)<>'77',yourfield)

Thanks!
