It seems your function name is incorrect.

The function name in your script file does not match the one configured in the form event handler.

Also you can use the following function that is improved version:

function checkForDuplicates(executionContext) { var formContext = executionContext.getFormContext(); formContext.data.refresh(false).then(function success() { var duplicateFlag = formContext.getAttribute("eem_ContractDupeFlag3").getValue(); if (duplicateFlag === true || duplicateFlag === 1) { var alertStrings = { confirmButtonLabel: "OK", text: "A record with the same combination of fields already exists.", title: "Duplicate Warning" }; var alertOptions = { height: 120, width: 260 }; Xrm.Navigation.openAlertDialog(alertStrings, alertOptions).then( function success() { console.log("Alert closed"); }, function error() { console.error("Error showing alert dialog"); } ); } }, function error(err) { console.error("Error refreshing data: ", err.message); }); }

Thanks Joseph! I tried this & got a 0x83215603 error, so added a setTimeout error (amended code below) that runs - but I get no dialogue pop up even though the criteria is met, if you can help that would be great as I am stumped. TIA

function checkForDuplicates(executionContext) {
var formContext = executionContext.getFormContext();
formContext.data.refresh(false).then(function success() {
var duplicateFlag = formContext.getAttribute("eem_ContractDupeFlag3").getValue();
if (duplicateFlag === true || duplicateFlag === 1) {
var alertStrings = {
confirmButtonLabel: "OK",
text: "A record with the same combination of fields already exists.",
title: "Duplicate Warning"
};

var alertOptions = { height: 120, width: 260 };

// Adding a delay using setTimeout
setTimeout(function() {
Xrm.Navigation.openAlertDialog(alertStrings, alertOptions).then(
function success() {
console.log("Alert closed");
},
function error() {
console.error("Error showing alert dialog");
}
);
}, 3000); // 3000ms = 3 second delay
}
}, function error(err) {
console.error("Error refreshing data: ", err.message);
});
}

Hi, just realised my field name didn't have capital letters in - revised this and it is working beautifully :)

Thank you so much for your help :)

In Event handles you have to mention function name rather than the file name...

So function name will be "checkForDuplicates"
