Create elevation grid - Inverted values

Hi, im rather new to GM and I'm trying to create an elevation grid from Depthpoints. This is for seabed data, but the results I'm getting are inverted, so going up instead of down. What can be causing this? Is there a way to invert the result?

    If your elevation data values can be manipulated in Excel try multiplying by -1 to invert e.g. 10 x -1 = -10

    There is a far simpler & better way of doing this. Open the Options dialogue for the elevation layer (double click or right click on the layer in the Control Panel). Select the Alter Elevation Values tab and change the scale factot to -1.
