Student here trying to figure out the mosiac process. I have 9 DEM's I need to mosiac. Here's what I've done and I continue get an error.

extents - union of inputs
cell size -100 (meters)

spatial analyst tools > map algebra > raster calculator

Here's my expression:
Mosiac ("casnerbutte", "cornville", "lakemontezuma", "loybutte", "mundsmtn", "mundspark", "pagesprings", "sedona", "wilsonmtn")

Any suggestion, what my expression should be or anything you see I'm doing wrong. Thanks in advance
