timestamp How to Add a day in system parameter timestamp

[Lepidoptera]

I am planning to use the tomorrow's or yesterday's date into a button as a query parameter using the  [@cbTimestamp*]. I tried using DateAdd(day,1, [@cbTimestamp*]) function but it displays just the text of the function and not a date.

I solved this problem by putting a function call on my button's onclick.
Here is the snippet of my function:

<button type="button" onclick="redirectPage()">Reset</button>

function redirectPage(){
  var myDate = new Date();
  myDate.setDate(myDate.getUTCDate()+1); //you can also use getDate() to get the local time on client
  //you can also subtract the date to get yesterday's date

  window.location.href="./search.php?cbResetParam=1&from="+myDate.toLocaleDateString()+"&to="+myDate.toLocaleDateString()+"";
}
