Giro Suspense doesn't balance

Hi all, my problem is that I recently returned to payroll to correct an entry error for an employee, I have done this before without problem however on this occassion the correction failed to be reflected in the bank account. On inspection of the Giro suspense account it shows the payroll correctly but the balancing entry to the bank current account has not been made. So Giro suspense now shows a minus balance. My first thought was to rectify this with a journal entry but the software does not allow suspense accounts to be changed in this way. I discovered the problem when my bank statement reconciliation failed to balance with quickbooks, I am using quickbooks pro I could of course just make a cheque to payroll expense to balance the reconciliation but I do not like to leave the suspence account showing a imbalance. Any ideas gratefully received. APR
