Can you suggest me how can I multiply the vale which was selected in combo box with a text box ??
I have created form of Final Invoice through Adobe pro 9. In that copy I have used the calculation method available to bring the total of amount. Now for calculation of GST(Tax) which may varies from 5% to 18%. So I want to multiply the value of percentage which was selected in combo box with the Total amount mentioned in text box.
If the fields are named GST and Total, use this formula under the Simple Field Notation option of the Calculate tab in the field where you want to display the result: Total * (GST/100)
