Help with YoY % measure

I am new to power BI. I am using the below formula. However when "PY TD MARKET SHARE" has sales and PY Total market share is $0, it is showing 0.00% which is not correct. it should show "100%" and when "PY TD MARKET SHARE" is $0 and PY Total market share has sales it is showing 0.00% iwhere as it should show -100%. 

 

IF(SUM('NPD workflow'[PY TD Market Share])=0,0,IF(SUM('NPD workflow'[PY Total Market Share])=0,0,SUM('NPD workflow'[PY TD Market Share])/SUM('NPD workflow'[PY Total Market Share])-1))

    Dimps , Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.

    First refer if below can help

    various ways to deal with this year last year

     

    YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD('Date'[Date],"12/31"))
    Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year),"12/31"))
    This year Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR('Date'[Date]),"12/31"))
    Last year Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year)),"12/31"))
    Last to last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-2,Year),"12/31"))
    Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-1,Year))
    Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),SAMEPERIODLASTYEAR('Date'[Date]))
    last Year Sales = CALCULATE(SUM(Sales[Sales Amount]),previousyear('Date'[Date]))
    Average PY = IF([Average CY]=0,BLANK(),CALCULATE([Average CY],SAMEPERIODLASTYEAR("dCalendar"[Date])))

    //Only year vs Year, not a level below

    This Year = CALCULATE(sum('Table'[Qty]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])))
    Last Year = CALCULATE(sum('Table'[Qty]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])-1))
