Writing form value back to a field in a table.

[equipe9]

I have a form called Account with the following fields on it as textboxes which pull values from an underlying table called Account.

OriginalBalance
TerminMonths
DiscountFactor

Additionally there is another textbox called PaymentDue which has the following formula under the Control Source

=[OriginalBalance]*[DiscountFactor]/[TermInMonths]

This calculates the value of paymentdue as desired but I can not figure out how to write the value of paymentdue back to the paymentdue field in the Account table.

Is there an easy way to set some sort of proprty to do this?

I've tried writing an update query launched via a command button as follows also to no avail.

UPDATE Account SET Account.PaymentDue = [Forms]![Account]![txtPaymentDue]
WHERE (((Account.PaymentDue)=[Forms]![Account]![txtPaymentDue]));

Thanks in advance for your help.

I need to make use of this value multiple times so it would be extremely helpfull if I could write it back to a table.

Then create a query that can be referenced many times, and not the table
