Reconcile does not work for me

[Colin Scott]

Silly question:  when you started the reconciliation process, what value
did you enter as the account balance?  It should have been the closing
balance as shown on the statement you are reconciling.  Note also, that
first panel should show you a start balance equivalent to the opening
balance on your statement.  If it does not then you have not correctly
completed earlier reconciliations.  (Or, if this is a new installation
and this is the first reconciliation you have run, your initial account
balance did not agree with the closing balance on your last statement, or
it is not marked as reconciled.)
