Question : SSRS percentage equation

I am trying to divide number of quotes won (W) by Total # of quotes.

This isn't bringing back any returns:
Count(QUOTE.STATUS 'W') / Sum(QUOTE.STATUS) as %Won

Thanks

Answer : SSRS percentage equation

The problem is that your existing query doesn't summarize - it's detail. You can't mix this easily, and where would you even display it in the query output. However, assuming you simply want the output to use the same dataset as is returned by your query, you can generate it either by rewriting the query as a Summary-form query, or using the output of the existing query as the input to this query. I'm going to reformat the query to use the QUOTE table you reference:
