i have a checkbox column that registers a check mark when an amount is over $100. The sheet has a form for collecting data. i put in a the formula =IF(Amount20 > 100, 1, 0) in the checkbox cell. Only when data comes in from the form, it puts new data at the bottom of the sheet below the formula. how do i get the formula to apply to the entire column, catching the new data coming from the form?
