Error On Calculation using DLookup

[Leesha]

Hi,
I'm using the formula below to calculate sales tax for a store. I get the an error that is in the attached screenshot. I have checked all spellings an even resorted to copy and pasting them in the Dlookup section but nothing works. What am I doing wrong?

Thanks!

Me.RentFeeSalesTax = Round([Me.Contract18TierTotalFeePercent] * (DLookup("[Sales Tax]", "qryContract18And20TaxesLookup")), 2)

Does it help if you change

[Me.Contract18TierTotalFeePercent]

to

Me.Contract18TierTotalFeePercent
