excel - how to display a validation list with value from two columns of another tab? -

i have requirement need apply list validation in such way list should display info 2 columns (of different tab in same excel) combined "-" ? able display single column using named range unable display 2 columns?

how can accomplish this?

below problem helper column.for new record, not have values in helper column.hence, list doesn't display new records.

thanks in advance!

so need bit of roundabout: can download illustration sheet here follow steps. here screenshot: first:use helper column c, , concatenate values in a , b using next formyla:

=if(isblank(b2:b999),"",concatenate(a2," - ",b2))

drag , fill downwards until cell want, in illustration did until cell c99, cells in column b empty, blank cell in column c. second: create name in name manager (i named trimmedlist in example) , inquire refer next formula, re-create , paste in refers to:

=example!$c$2:index(example!$c$2:$c$99;countif(example!$c$2:$c$99;"?*"))

by way, sheet's name example. press ok , close name manager. third: select e2:e100 , click on info validation, allow list , re-create , paste next in source, click ok:

=trimmedlist

remember our name named trimmedlist. there go! can manually add together new entries , seek drop downwards menu! see values , not blanks.
