Forms :: Text Box Value Based On Two Other Textboxes

I have three textboxes , textbox 1,textbox 2, and textbox 3, I can change the value of textbox 3 based on the date of textbox 2 by using

if me. textbox2 < date then
me. textbox 3 ="expired"
end if

but I need it to look at textbox 1 as well and only change textbox 3 to "expired" if both conditions are true. example

if textbox 1 = "abs" and
textbox 2 < date
then textbox 3 = "expired".
end if
