What AM I Missing Using Between Statement With Dates

 Hi Folks

I cannot figure out why I am not getting all my data when using the BETWEEN statement with a date in one particular sql and not the other

Can anyone see what i am missing

Any assistance will greatly relieve my stress  :-)

Thanks

Jim
