Java script help - create and autoformat text callout

You're code makes no sense, you can't just make things up. To begin, there's no such thing as a "TextCallout" annotation. There is a "FreeText" annotation that can include a callout arrow.  The "addAnnot" function only needs to be called once And the information about where the callout arrow points needs to be included. 

As pointed out by Try67, there are many other errors in the code. Perhaps you should start by looking up the actual information on how to do this? 

Here's the JavaScript reference entry for the annotation object.

Sorry, here's the code:

// Function to create text callout and text field
function createTextCalloutAndField() {
// Get the active document
var doc = this;

// Create a text callout annotation
var callout = doc.createAnnot({
type: "Annot",
subtype: "TextCallout",
rect: [226.09500122070312, 1091.8299560546875, 484.81298828125, 1167.5699462890625],
fillColor: 0x00000000, // Transparent background
lineWidth: 1,
strokeColor: 0x000000, // Black border
fontSize: 10,
font: "Helvetica",
textColor: 0xFF0000, // Red color
});

// Set annotation properties
callout.name = "Text Callout";
callout.flags = 4; // Read-only

// Create a text field inside the callout
var field = doc.createAnnot({
type: "Annot",
subtype: "Text",
parent: callout,
rect: [5, 5, callout.rect[2] - callout.rect[0] - 10, callout.rect[3] - callout.rect[1] - 10],
borderStyle: "Solid",
borderColor: 0x000000, // Black border
fillColor: 0xFFFFFF, // White background
font: "Helvetica",
fontSize: 10
});

// Add annotations to the document
doc.addField(callout);
doc.addField(field);
}

// Create the text callout and text field on document open
this.addField("Open", "doc.createTextCalloutAndField()");

// Function to format pasted text
function formatPastedText() {
// Get the active document and text field
var doc = this;
var field = app.activeField;

// Check if a text field is active
if (field && field.type === "text") {
field.setFont("Helvetica");
field.setFontSize(10);
field.setTextColor(0xFF0000); // Red color
} else {
app.alert("Please select the text field in the callout to paste into.");
}
}

// Add a custom paste event handler
app.addPasteHandler(formatPastedText);
