Multibox - Display only selected values

[stuwannop]

Hi Everyone

I have a multibox set up which allows the user to select a year value. The year in the raw data goes up to 2099 (this can't be helped) but I only want the user to be able to see 2013 & 2014. Filtering the core data is not an option, I need to add an expression  in the multibox can  someone help?

Thanks in advance.

Try an expression like =if(year=2013 or year=2014,year) instead of using the field name
