Length Field Shows No Data

Hi All,

I have bored piers of depth 1.6 meters each, and quantities of 71 and 28 piers respectively. I would "Length" column to display the total length of piers as: 113.6m, 44.8m

• Quantity × Depth = Total Linear Meters
• For example: 71 × 1.6 m = 113.6 m, and 28 × 1.6 m = 44.8 m.

Is there a way around to have the "Length" column reflecting this calculated value results (e.g.,113.6m, 44.8m) rather than showing nothing?
