Local County Tax Payroll Calculation

I set up a Local County Tax Payroll Calculation - for two counties. Each calculation has the Tax Type 13-Local Income Tax. which automatically puts in the Calc Type  - Deduct from Employee and Method 17-Tables.  The CR account is a Current Liability in which I also set up SubAccounts for each county tax.  I set up the Tables in 5-3-6.  I included the appropriate Payroll Calc in the relevant employee records.  When doing a Trial Compute, nothing is calculated in the Employee record.   Any help would be appreciated!  Thanks
