SSRS - Ratio not calculating correctly

I have a drilldown report and Group results for ELA/MHG are not calculating RATIO separately....  Any idea what I am doing wrong?

Ratio=Sum(Fields!ccSTA_MED.Value, "ReportDB")/(Sum(Fields!ccSTA_MED.Value, "ReportDB")+Sum(Fields!ccSTA_TELE.Value, "ReportDB")+Sum(Fields!ccSTA_ICU.Value, "ReportDB"))

Attached is an Excel Sample of SSRS report.

It is possible that you might be missing a group if you have nested groupings (parent/child groupings) since you mentioned that you have a drilldown report.  
For example if you have four groups nested in hierarchical fashion (e.g.  Group1 -> Group2 -> Group3 -> Group4) and by chance your columns only accommodate three groups (e.g. Group1 -> Group2 -> Group4) for example, then the values would be different and your result would not calculate correctly.


Also, based on your Excel Spreadsheet, you need to provide a condition in your expression (e.g. using IIF) to determine if the values in the row are ELA or MHG in order to calculate the correct ratio for each row.  It looks like your aggregate functions is aggregating for both ELA and MHG.

I really wouldn't want to put an iff condition, then otherwise it wouldn't be dynamically calculating groups.  I figured out the problem.   There I was using the "ReportDB"

Sum(Fields!ccSTA_MED.Value, "ReportDB")/(Sum(Fields!ccSTA_MED.Value, "ReportDB")+Sum(Fields!ccSTA_TELE.Value, "ReportDB")+Sum(Fields!ccSTA_ICU.Value, "ReportDB"))

This solved the problem...
Sum(Fields!ccSTA_MED.Value)/(Sum(Fields!ccSTA_MED.Value)+Sum(Fields!ccSTA_TELE.Value)+Sum(Fields!ccSTA_ICU.Value))
