How to set up employer matching contributions in payroll

[pgsinclair]

Our 401(k) plan matches employee contributions, up to 3%. Normally this works correctly. However, in this unusual situation, this employee has a flat $10 deducted from his check. Most weeks, the 3% does not exceed the $10. However, in some weeks that he works overtime or receives bonuses, the 3% exceeds the $10. How can we set up the deduction code to match 3%, but limit it to the $10? I have tried using the limit box, but this limits the annual contribution limit, not the per paycheck limit. Any help would be greatly appreciated.

Thank you.
