IPmt function in Access 2003

I am trying to calculate the monthly payments for a repayment mortgage using
the Pmt function

Pmt(sum([InterestRate]/1200),sum([MortgageTerm]*12),[MortgageAmount],0,0)

The result is always incorrect by about £200, I am checking my calculations
against online mortgage calculators and my own math. Can somebody tell me
where I am going wrong or suggest another way of calculating this.

Dave Clissold,

Can you please provide the following?

The input data.

The output data.

The "correct" calculations.

The datatypes for [InterestRate], [MortgageTerm], and
[MortgageAmount].


Sincerely,

Chris O.
