How to change variable with another variable with "variable input"?

[YanivZi]

I am trying to change variable with another like $vPersonA -> $vPersonB

I've added "Variable Input" from the Qlik dashboard bundle, with the name variable $vPersonA (as button) then I selected  fixed values and added this in value as alternative  ='($vPersonB)', now when the sheet is loaded it has the data from $vPersonA but when I click on $vPersonB it does not change the data.

found the problem. its should be $(vPersonB) not ='($vPersonB)'
