Parameter Query with Parameter value(s) or no entry returns all

[Bettergains]

Hello:
I used to know how this was done. I want to set up a parameter in the query
such that upon enter, the result set returns either a) based on value(s)
input in the parameter dialogue; or b) user enters nothing and resultset
returns all.

Your help is always invaluable.

Put something like this in the criteria section for the field you need to
have the parameter in.

LIKE "*" & [Enter Value] & "*"

Thanks. I have exactly that. Now I would like to expand on it and be able to:
add multiple values

so:
add [a single value] or [multiple values] or [nothing and return all]

Your expertise is very helpful~
