Hi,

Your description is a bit vague but if i understand correctly, you can use a button to make the calculation. I havent included any logic to protect against empty fields.

form1.#subform[0].btnCalculate::click - (FormCalc, client)

grandTotal = subTotal + (subTotal * (salesTaxCbo / 100))

Assuming:

salesTaxCbo - Checkbox prefilled with tax percentage

subTotal - Numeric field

grandTotal - Numeric field which gets calculated amount.

btnCalculate - The button to calculate the grand total
