Applying Invoice's to Manual Check not calculating

I have Calculated the invoice's 10 times and come up with the same amount that I wrote on the Manual Check each time, but when entered into an Invoice Batch then applyed to manual check in Payables the total comes out with a 0.10 difference, it's driving me mad, and I don't understand why it isn't calculating properly, now I will have to adjust and add a credit to make the account balance. Is there any known reason for this glitch?

Do any of the invoices have terms that allow an early payment discount?

There are no known glitches with invoices not totalling to the payment amount correctly.

No, none of the invoice's have early payment discount terms. There were two regular invoice's and one credit note, and have added them manualy with a claculator and using excel, both ways my numbers came out the same, but when entered into Payables the total came out with 0.10 owing.

Opps, I found the mistake, my mistake, thank you for your time and help

Glad to hear things are better.
