Error "One or more of the input waves are not supported." in Interpolate3D

Hi,

I have a problem with Interpolate3D. The problem is that when I tried to execute this command it returns error message saying "One or more of the input waves are not supported.". I am pretty sure I have checked all of the input and flags that they should conform with the command's syntax. Here's what I execute

Interpolate3D /RNGX={0.8,0.012,80}/RNGY={1.25,0.012,80}/RNGZ={0.1,1,1}/DEST=fu_interp triangulationWave=M_3DVertexList, srcWave=fu_xyz

fu_xyz is a 2D and 4-column wave with the first three column specifying the x,y,z triplet for the corresponding fu(x,y,z) in the 4th column. The wave M_3DVertexList was first obtained using triangulate3d using an input of 2D and 3-column wave (e.g. wave name xyz) where its three columns are identical to the the first 3 columns of fu_xyz. I guess these all already satisfies interpolate3d requirements.
