Help Copying an Array Formula down an Entire Column

the $ usually fixes a cell or range

you have
=SUM(IF(IF(K$2>=V3:V5,V3:V5-V2:V4,$K$2-V2:V4+1)>0,IF(K$2>=V3:V5,V3:V5-V2:V4,$K$2-V2:V4+1),0)*W2:W4)
going down one row - but the K$2 changes to K$4
=SUM(IF(IF(K$4>=V3:V5,V3:V5-V2:V4,$K$4-V2:V4+1)>0,IF(K$4>=V3:V5,V3:V5-V2:V4,$K$4-V2:V4+1),0)*W2:W4)

do you want that to happen

to fix a row us the $
so if you want
V3:V5,V3:V5-V2:V4
NOT to change as you copy down the rows use
V$3:V$5,V$3:V$5-V$2:V$4
that fixes the row

if you want it to change as you copy down then leave the $ off
