Array Formula Error -Too Few Arguments

[Rcaaa]

=IF(ROWS(B$10:B10)>$C$2,"",INDEX(Task2.0!A$2:A$3500,SMALL(IF(Task2.0!$A$2:$A$3500=$B$2,IF(Task2.0!$H$2:$H$3500<=$E$2,IF(Task2.0!$H$2:$H$3500>=$D$2,ROW(Task2.0!$H$2:$H$3500)-ROW(Task2.0!$H$2)+1)),ROWS(B$10:B10))))

Can someone tell me what I am missing in the array formula above? I am receiving an error saying that I have too few arguments. I am trying to show the tasks based on the project ID and a date range.

Sheet - Task2.0
Column A = ID
Column H = Date

maybe something like...

=IF(ROWS($B$10:B10)>$C$2,"",INDEX(task2.0!A$2:A$3500,SMALL(IF(task2.0!$A$2:$A$3500=$B$2,IF(task2.0!$H$2:$H$3500<=$E$2,IF(task2.0!$H$2:$H$3500>=$D$2,ROW(task2.0!$H$2:$H$3500)-ROW(task2.0!$H$2)+1))),ROWS(B$10:B10)))) control shift enter
