Reimbursing an employee for picking up supplies with there own money

SOLVED

I have tried several things and it always still ends up with multiple entries.. I am trying to reimburse an employee who picked up some supplies( From Staples) and paid with their own money. I have set up a G/L acct specifically for employee reimbursements, and entered the receipt into the suppliers purchases (under G/L Office supplies). But here is where I can not wrap my mind around the rest. How do I add this to the employee cheque, and have it reflect that the purchase invoice(for Staples) is paid? Is this possible to do that?
