How to add multiple items and multiply it - need help with Javascript

[fionah34496716]

I would like to add about 3 columns and multiply them by another column and I'm having some problems writing the javascript.

I would like to add totals with the following headings:

Hotel1+Parking1+Mileage1*USexchange1 .

Could someone provide me with the instructions?

Just add parentheses and put the exact formula above under the Simple Field Notation option in the Calculate tab.

You don't need JS.
