Hi there!

Im wondering if you could help me out as im trying all kind of tricks to make what i want it to work, i have tried =if(or(a1>b1,a1<b2), "x","y") function, (b1=01/01/2005, b2= 31/12/2005) it will work but if no date has been input then it still show x

'm looking for fornulas/function that will help me with my work, see below:
between 01/01/2005 and 31/12/2005 = "x"
between 01/01/2006 and 31/12/2006="Y"
if no date input then ignore it or leave it blank.

I would be grateful for your kind support.

Craig
