Most current date query

[Guest]

I have a table with dates as the records and prices as the fields. I want to
do a query where a person can input a date and will get either that date's
prices or the prices on the next previous date before their input date.

<= gives me all of the dates prior to the one they input
What is the proper criteria to get the input or next prior date?

If the idea of subqueries is new, this might help:
