weighted Avg

hi i'm trying to create a weighted avg 

 
 
 

 the calcultion should be per major gener - (imdb rating*imdb vote)/sum(imdb vote)

i try to do this:

 

Measure = 
 VAR X = SUMMARIZE(imdb2,imdb2[Major Genre],"sum",DIVIDE((SUM(imdb2[IMDB Rating])),SUM(imdb2[IMDB Votes]),ALLEXCEPT(imdb2,imdb2[Major Genre]))
 )
RETURN 
IF(HASONEVALUE(imdb2[Major Genre]),CALCULATE(SUM(imdb2[IMDB Votes]),SUMX(X,[sum]*imdb2[M_Profit])))

 

i got this error - The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value.

@Reut_123  Few things are incorrect here:

ALLEXCEPT is a table function as well as a CALCULATE modifier, the way you are using it is incorrect.

Use of SUMX is incorrect, CALCULATE's 2nd argument onwards can only take boolean operations, tables, or CALCULATE modifiers.

 

Unfortunately writing about these 2 points will take a lot of pages so its not possible to explain the issue, so you will have to read the documentation.
