Too Few Parameters - UPDATE SQL

[jgelpi16]

I have the below code. I have looked over this time and time again. Not quite sure what is throwing the error message. A fresh set of eyes would help. Thank you.

    Dim varUser As String
    Dim varDate
    Dim varEntityID
    
    varEntityID = Form_AA_frmBankGarn.txtPriEntityID.Value
    varUser = Form_FrmMain.RV.Value
    varDate = Now()
    mySQL = "UPDATE LevyTable SET [LastUpdateUser]= varuser WHERE [PriEntityID]='" & varEntityID & "'"
    CurrentDb.Execute mySQL, dbFailOnError

Keep getting the error message:

"Run-time error '3061':
Too few parameters. Expected 1."

mySQL = "UPDATE LevyTable SET [LastUpdateUser]= varuser WHERE [PriEntityID]='" & varEntityID & "'"

varuser needs to be concatenated into the string, similar to how varEntityID was.
