Range issue when I drag and copy SUMIF

When you select the range then for the lets say F1:F200 press F4 key in your keyboard so that it makes is absolute reference and it will look like this
$F$1:$F$200 you can also manually put the dollar signs, but pressing F4 will do it for you easily.

You have not attached the data, but from what I can guess, you need to use the absolute reference in your range and mixed reference cell for the cell of criteria

So your formula should be something like this

=SUMIF($F$1:$F$200,$K20,$G$1:$G$200)
a dollar sign in front of Column $A1 means column will not move but row will move
A$1 means row will not move but column will move
$A$1 means both column and row will not move.
A1 means both column and row will move
