Depths out of order when outputting.

Hi All,

I'm having some trouble trying to create a soilbore profile which had a stockpile on top. The stockpile was .45m high AGL, below it was natural ground which was augered to 0.3m BGL. Ideally it'd look something similar to the table below:

Depth - mBGL     |   Lithological Description. 

-0.45 m Stockpile - red
-0.3 m Stockpile - grey
-0.1 m Stockpile - red
Ground level HDPE liner - black
0.2 m Natural sand - blue

To represent the above ground stockpile, I entered the stockpile depths as a negative. This almost worked, except the order of the depths is wrong, it has just sandwiched the -0.45m depth at ground level, in the same cell/box as the -0.1m data. This results in it looking like:

Depth - mBGL     |   Lithological Description. 

-0.3 m Stockpile - grey

-0.1 m

-0.45

Stockpile - red

Stockpile - red

Ground level HDPE liner - black
0.2 m Natural sand - blue

Does anyone know how I can change this so the log appears as it does in the first table? 

Thanks,

Andrew Mortimer
