I have set up a table for one of my project in http://sg.propertylaunchnetwork.com/hausserangoongarden under the tab named UNIT TYPES & FLOOR PLANS. Using the formula =SUM(G2:G27) at the footer besdie the label "Total Units". The table indicates 1557 for the total units. In actual fact, there's only total units of 97. How do I resolve this issue?
