Sub totals and grand total are incorrect

[Sagejah9]

Hi 
I created a dax measure to sum total sales but it has a few if conditions to go through before doing the calulation. First I am checking for the currency then check if a line item is in a list of specified items. if both conditions are true then it will do currency conversion in USD and multiply the some by -1 to make it positive. the numbers in the column are negative hence I want to multiply by -1 to make it positive. 
When I put the function in the matrics table it does the conversion and sums the total however its not summing the results as positive. 
How can I fix this. 
var x = values(table[numbers])
Measure  if(selected currency = "CAN", if x in {1,2,3,4,5,6,7}, calculate(sumx(table2, (table2[sales_amount]/related(currency_table[fx_rate])*-1)),calculate(sumx(table2, (table2[sales_amount]/related(currency_table[fx_rate])))

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376

Thanks @Greg_Deckler , I still dont see where I would use the Hasonefilter.

@Sagejah9 Generally using ISINSCOPE and HASONEVALUE is better than HASONEFILTER for these sorts of things.
