In order to gain control over Notes "Computed for Display" fields for display in a Web browser, wrapper your formula language with the HTML tags you wish to use. This will allow more control over how you want your data to be displayed in a web browser. For example, in order to format a dollar value place the following code in the value section for the field: "" + @Text(DollarAmount;"C,0")...
This will format the font face and color and right align the data in the field.
"[<FONT STYLE='font size="12";text-align="right";color:black'>]" + @Text(DollarAmount;"C,0") + "[</FONT>]"
