Formating problem in a report

[SeniorCitizen]

A table with a calculated field with field properties as follows:
Expression UnitRev-MF1-MF2-Mf3
Result type

What is the formatting problem?

Is UnitRev-MF1-MF2-Mf3 a field name or attempting arithmetic?

What is "Result type"?

[ranman256]

select the report's textbox , set the format property.

Result Type Double
Format Standard
Decimal Places 2
Text Align General

The calculation works properly and nis displayed in Data Sheet View as 1,688.60.
When putting that field in a text box in a report it appears as 1688.6.
I have tried changing the Result type but nothing I have changed will display in the report as it is in the table.
There has to be some simple thing I'm missing.

Any Thoughts
Thanks
