How to populate a cross reference field using a Custom Object

[AlexanderHatfie]

I'm currently storing a variable that contains the Tracking ID from another application that has a cross reference into the app that I want to make this Custom Object. I'm not sure where to begin to be able to perform a lookup to reference that Tracking ID to the record in the cross referenced app. Would anyone be able to point me in the right direction?

@hmealstrom can you post your custom object?

Thanks for your answer @DavidPetty  Here is my code

´´´

<script type="text/javascript">


function setXrefFieldValues(fieldId,values) {
field = $CM._fields[fieldId].clientId;
ArcherTech.UI.ReferenceField.CurrentLookupField = $find(field);
var currentField=ArcherTech.UI.ReferenceField.CurrentLookupField;

if(currentField) {
currentField.setLookedUpRecords(values);
if (currentField.get_isInDdeCondition() && Sys.WebForms.PageRequestManager.getInstance().get_isInAsyncPostBack()) {
var endRequestHandler = function () {
ArcherTech.UI.ReferenceField.UpdateCurrentField(values);
Sys.WebForms.PageRequestManager.getInstance().remove_endRequest(endRequestHandler);
};
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequestHandler);
} else {
ArcherTech.UI.ReferenceField.UpdateCurrentField(values);
}
}
}

Sys.Application.add_load(function()
{
var vlField = 26923; // Values List Field
var deleteXrefFields = [27275]; // Id of Cross-Reference Field


var selectedValue = $CM.getFieldValue(vlField);
var idVltoclear= ['88628:0']; // Value Id of Values List Field


if (selectedValue[0] == idVltoclear[0]) {
console.log("The value is selected 88628:0"); // Flag to see output in console terminal
setXrefFieldValues(deleteXrefFields[0], []);


}


console.log(selectedValue)
});



</script>

I have two errors:

• When I enter the record. It is stuck in the loading screen and the console.log says

Record.aspx?id=32647…3ef773399488e7e:620 Uncaught TypeError: Cannot read properties of null (reading '0')

• And when i manage to bypass the loading screen. The code works but in the console log the following message appears to be repeating indefinitely
