worksheet functions

[ploh]

I'm trying to utilize the worksheet ability of Vectorworks to create a materials list for my project. I am trying to create separate fields that will display the height, width and depth of an object. Looking in the manual, I saw the functions for height and width, but not depth. I tried using them, but they are not giving me the correct information. For instance, if my object has a height of 42.75 inches, the worksheet displays the height as 45.893. I entered the function in the worksheet column as "=HEIGHT". I am new to using worksheets, am I using the function incorrectly?

Also, are there any resources that have detailed information on how to use worksheets and explain the use of functions? I've read the manual and cannot seem to piece this all together so that it gives me the information I want. Thanks!
