I'm doing an assignment for a mapping class and I'm literally stuck trying to create a DEM file using the grid calculator under SAGA. I'm following the directions we were given and I have searched for other solutions such as saving as a temporary file and cleaning out my hard drive and I still get the error the layers were generated.

I'm a beginner using QGIS since I'm in an entry-level class. I've read other solutions but nothing is working and I have to do this step to make this mosaic DEM map for a grade. (copy and pasting the error) any solution would help because I'm at a loss.

I have the parameters set as 0 nearest neighbor, used a formula, and the data type as [7] 4 byte floating point number. I have my two layers used in our worksheet set as the grids.

You can check the 'Log Messages Panel' in QGIS main window to find more information about the execution of the algorithm.
