Field help (VATBXFOR)

Enter a formula for a TotalVAT box type.

There are specific formula syntax rules that must be followed:

You must enclose each VAT box within single quotes. For example, to include the total amount of two VAT boxes named B1 and B2, the formula would be: ‘B1’ + ‘B2’

The formula can only include VAT boxes previously defined, otherwise you receive an error. That is, a VAT box that is defined on a line above the line with the formula.

The formula can include complex operators such as:abs(-‘B1’ - ‘B2’)

A formula that includes a range of VAT boxes is not possible.
