    Count + between + parameter function

    Title makes no sense.

    I have a field, TestDate, and I want to count the number of patients whose TestDate is between xx/xx/xxxx and xx/xx/xxxx. I want the query to ask me for those two dates.

    This is what I have so far:
    SELECT COUNT(TestDate) AS Tested


    FROM Patient (My Table)
    WHERE TestDate='BETWEEN [Between?] AND [And?]';

    When I open the query, it asks TestDate and gives a value of 0 whatever I put in. Could someone tell me what I'm doing wrong, please?
    I've never used SQL before, so it would be great if someone knew a good site where I can learn about it.

    Does this work?

    SELECT COUNT(TestDate) AS Tested
    FROM Patient (My Table)
    WHERE TestDate BETWEEN [Between?] AND [And?]

    Thanks, I've removed the quotes and it works spiffingly. It's always things like that which I get caught on. Thank you!

    Happy to help. You also had an equals sign in there that would cause a problem. It's either = or Between, not both.
