Wrong sum

Anonymous Not quite following this one. Seems like you need a measure but hard to know for sure. Sorry, having trouble following, can you post sample data as text and expected output?

Hi Greg. I found this article by you - https://community.powerbi.com/t5/Quick-Measures-Gallery/Measure-Totals-The-Final-Word/m-p/547907

Used the methodology in the article but issue persists. This is my m_single -

This is my m_total - 

Outstanding Qty (column 2) is a calculated column (Quantity - Quantity Shipped). Outstanding qty m_single and m_total are measures. I put them side by side for comparison. The correct outsanding qty for my selection here is = 3+5+15+25+30 = 78, the sum of the outstanding qty column. But both the m_single and m_total columns are giving me incorrect totals. Could you please point out if there are any mistakes in my m_single/m_total formulas?
