if getselectedcount doesn't work

[eliezer7]

hi.  I do not know why this expression doesn't work.

=if((getselectedcount(Year) >=2 OR getselectedcount(Full_Student_Name)) >=1, '-', Avg(SumMath4_Percentages))

any ideas?

thanks

Can you try below expression?

=if((getselectedcount(Year) >=2 OR getselectedcount(Full_Student_Name)>=1),  '-', Avg(SumMath4_Percentages))

I already found the solution. It doesn't work if I use masteritems with the following =Year & ' ' and =Full_Student_Name & ' ' in the expression.
Thank you
