Trying to run a contour line layer through modelbuilder (topo to raster), but when I select the source layer as parameter, it gives error 000800, claiming "ELEVATION" field is not accepted, even though it's part of the fields (OBJECTID, ELEVATION and shape_length are the only fields.
This only happens if I run the topo to raster through modelbuilder, if I use the tool by itself it runs fine.
