I am trying to work out a way to set up my Structure Table so that I can show either the Inner Pipe Width OR Headwall Base Width to avoid having Question Marks showing in my Table? Is there a Function in the expressions that equates to a Non-Existent or Null Parameter. Ie.
IF({Inner Structure Width}=???,{Headwall Base Width})
Also, Is there a way to hide Structures from a Table, in particulat, Null Structures?
Thanks. Ross.
Perhaps some random mathematical formula that returns a normal answer with a normal number, like
IF (({Inner Structure Width}+2=({Inner Structure Width}*2+1)/2,{Inner Structure Width},{Headwall Base Width})
Or something more normal like
IF ({Inner Structure Width}>0,{Inner Structure Width},{Headwall Base Width})
