Help with SQL Syntax

Question

Hello,
I've got a form that returns results from a MySQL table
[tasks] based on three parameters:
task_resource
begin_date
end_date
Here is my code in the record set dialog box:
SELECT *
FROM tasks
WHERE (task_resource = varName) AND (begin_date BETWEEN
varBeginDate AND varEndDate OR end_date BETWEEN varBeginDate AND
varEndDate)
ORDER BY tasks.begin_date
I thought it was working fine until I ran into a problem. The
SQL statement doesn't work if I want to see only those tasks begun
and completed on the same day. For example, I entered begin_date
02/22/08 to end_date 02/22/08 because I only want to see tasks
started AND completed on that date. But my SQL is set up (with the
"OR") so that it's returning tasks with a begin_date of 02/21/08
and end_date of 02/22/08.
How can I correct my SQL? Not sure how to do this if I take
out the OR condition.
Thank you.

SELECT *
FROM tasks
WHERE (task_resource = varName) AND ((begin_date BETWEEN
varBeginDate AND
varEndDate) OR (end_date BETWEEN varBeginDate AND
varEndDate))
ORDER BY tasks.begin_date
