So I have created a script,

I have multiple defs, but want the one with the highest value
def a = if open is 12 then 1 else 0
def b = if close is 21 then 2 else 0
def c = if high is 8 then 3 else

I want it to return the max of the 3, so lets say we have true statements to a and b, that's 1 and 2 . so the max is 2,between both so I want B.

if MAX(a, b, c) worked i'd use it but im out of luck

Nest the Max() function as many times as needed.
Example:

Max(variable1, Max(variable2, variable3))

Thank you but I'm already past this . would you happen ro kmow if there's a way you could put chart bubbles all the way to the right?

If your referring to Chart Labels the only way to display them at the right is to add spaces in the text string on an otherwise blank label. Chart Bubbles can be placed anywhere on the chart. The two different functions are..
AddChart()
AddChartBubble()

Ah. What I mean is I have a highestall horizontal line, and I want the text to appear all the way on the right to that line. A label only places it in the top I believe? Correct me if I'm wrong.

You have that correct. A Label is always at the top. A bubble can be anywhere on the chart.

Here's a typical method to display a label in the Right Expansion Area (make sure you have your Expansion Area set to at least 10 bars).

def BubbleLocation = IsNaN(close[1]) and !IsNaN(close[2]);

AddChartBubble(BubbleLocation, "Variable", "Description", Color.Yellow);
