I want to create conditional drop down list when user fill the year in column A and in column B is filled the range which is taken from list defined in column E. How can I do it?
Here is a solution which requires a few helper columns

=NUMBERVALUE(LEFT(J3;4))
=NUMBERVALUE(RIGHT(J3;4))
=L3-K3
=NUMBERVALUE(K3)
=IF(($N3+COLUMN()-COLUMN($M3)-1)<=$L3;$N3+COLUMN()-COLUMN($M3)-1;0)
=IF(COUNTIF($N$3:$Z$17;A4)=1;A4;"")
=OFFSET($C$4;;;COUNTIF(C4:$C$1000;">1");1)
=INDEX($J$3:$L$8;MATCH(E3;$K$3:$K$8;1);1)
Replace semicolon with komma if your local Excel version needs it.
You could combine some formulas to have less helper columns.
