(@YearFrom = 'Year' and @YearTo = 'Year')

@YearFrom変数と@YearToが文字列であることを暗示しますが、それらを Int32 として宣言します

<asp:SessionParameter Name="YearFrom" SessionField="YearFrom" Type="Int32"  ConvertEmptyStringToNull="true" />
<asp:SessionParameter Name="YearTo" SessionField="YearTo" Type="Int32" ConvertEmptyStringToNull="true" />

文字列 'Year' は int 型ではないため、実行中に失敗します。
