Maybe i should describe my problem a little bit better.

Im working with WeakAuras 2 And i have a bar to observe my Blood Shield of my DK.

This is the function i use to show how much damage my shield can block:

function () 
    local shield_value = select(15, UnitBuff("player", "Blutschild")) or 0;
    shield_value = math.floor(shield_value/1000);
    
    local max_health = UnitHealthMax("player");
    max_health = math.floor(max_health/1000);
    
    return string.format("%uk/%uk", shield_value, max_health);
end

My Trigger Code:

function()
    return true
end

My Reverse Trigger Code:

function()
    local a = UnitBuff("player", "Blutschild")
    return a == nil
end

And now i need Code for the duration so that my bar
shows how much time is left until my shield expires.
If i use one of your codes posted above i get the
posted lua errors and the bar starts randomly in the
middle of the bar and decreases.
