Your data in word document is a big pain to work on....
XL files is always easier....
anyway, if you have a Num Month field, as in Month numbers then create a flag in back end like below...
if(Num_Month>=4,1,0) as FYTD_Flag, <<< This may be a preceding load depending on how the data is loaded.
After having that flag in front end
You may need 4 different expressions
1. Sum({ < Year={2018} >} Production) >> Selected Month
2. Sum({ < Year={2017} >} Production) >> Selected Month
3. Sum({ < Month = {"<=$(=num(Month))"} , FYTD_Flag={1},Year={2018} >} Production) >>2018 YTD
3. Sum({ < Month = {"<=$(=num(Month))"} , FYTD_Flag={1},Year={2017} >} Production) >>2017 YTD
Or provide a clean data in XL file to work on?
I tested it on my end and adding a flag will only start the Month from Apr, this will be static
