sameperiodlastyear and % change

Hello,

I have a problem with formula "sameperiodlastyear" and % change last period. It shows wrong value when the period (month, quater, year) is not chosen on slicer.

1) I created a date table using the calendar function of Powerbi.

2) I added a function: 

Lastyearperiod = CALCULATE('Sales Valus PLN'[Total sales], SAMEPERIODLASTYEAR('Timedimension'[Date]))
3) then:
% last period = CALCULATE( DIVIDE( 'Sales Valus PLN'[Total sales] - [Lastyearperiod], [Lastyearperiod]))
 
It works great until I dont chose period (month, quater, year) on slicer. If a slicer contains all periods it shows a wrong value. I want to add a funcion if date is not chosen show blank, but I really dont how. Please help me.
I created a relationship beetween columns:

Any tips on where I'm going wrong here would be hugely appreciated.

@paulinamaj you never clarified, you mentioned that you are selecting a date and now you have totally different explanation. Read this post to get your answer quickly.

@paulinamaj you can tweak your measure like this:

 

% last period = 
IF ( HASONEVALUE ( YourDateTable[DateColumn] ),
CALCULATE( DIVIDE( 'Sales Valus PLN'[Total sales] - [Lastyearperiod], [Lastyearperiod]))
)

Hi, @parry2k thank you. But now it stopped working correcly, shows non value for all year, only for last year of date (I have to choose month, quater, year on slicer).
