Question : Date Comparison in MSSQL

Hello,  I'm trying to compare two dates from two inline views in my where clause.  

Both of the selects in my views work correctly, these fields are dates.  

I want to verify that avail.period is before the date alloc_end.alloc_end from another inlline.

Like....
Where
avail.period <= alloc_end.alloc_end AND.....

Thanks in advance, this simple issue is killing me.

Use the BETWEEN operator.

SELECT * ...
WHERE avail.period BETWEEN date1 AND date2
