Hi Hellmuth

It is possible to create formulas to calculate grades for the various grade items as described here

The formula follow the following rules and might look something like  below - 

• the rounded bracket need to go around functions
• square double brackets around the variables 
• Use  comma as separators
• the same number of left and right brackets needs to be used 

The formula will be similar to below - not sure if I have this right but similar concept to spreadsheet formulas

=sum([[SCORM]],[[ SCORM 2]],max([[SCORM3a]], [[SCORM 3b]]).[[SCORM 4]])/4])

Regards
