SUMIF OR SUMIFS functions with criteria as formula

Hi All,
Need help with SUMIF and SUMIFS formula, where in I want to set criteria in the formula as greater than or less than or equal to value derived from another formula. I am inserting the following formula but excel is not allowing me to enter the formula.

=SUMIFS($C$22:$C$30,$E$22:$E$30,>=LEFT(L21,3),$E$22:$E$30,<=RIGHT(L21,3),$A$22:$A$30,G22)

I am attaching an excel to explain the issue further.
