how to grad-out or other color when no button select

[ramrongala]

Hi Experts,

i have 4 button YT,MTD ,QTD, WTD , if i select any button it should be highlighted(green color) reaming buttons grad-out (gray color), up to here working fine BUT

If i select dates from Data-picker object buttons should be grad-out(gray color) 

i am using QlikSense June 2020 version .

at present i select dates from date object reaming buttons not grad-out, last selected button highlighted

please have a look below screens (i selected YTD and reaming buttons grad-out/other color)

i selected dates from Date object  but still YTD button highlighted 

I hope you guys understand my issue. please help ASAP.

Sorry Guys i forgot to mention logic i have created variable and pass the values each button

below logic i have used in buttons ( in Background color) .

YTD = if ( vButton=2, Green(),Gray())

QTD= if ( vButton=3, Green(),Gray()) 

MTD = if ( vButton=4, Green(),Gray()) 

WTD = if ( vButton=5, Green(),Gray())
