When validating a field change, can you get the previous value from a client script?  Also, how on earth do you alert() in the validateField without an infinite amount of alerts lol

You could load the record and keep it in a global and use that to compare values.

That's what I did. Still lame. I also wish I could validate it and pop up an alert lol

it goes on an infinite loop if I return false

Every time I click ok it triggers validateField

it shouldn't fire validateField until you click out of it

That's what I think too. But when I added the alert, infinite loop

sounds like maybe you have that backwards or something

Yeah. it only returns false if it gets to the alert

```let isValid = true;
const rec = ctx.currentRecord;
const tranId = rec.getValue('tranid');
if (_tranId === tranId) {
    return true;
} else {
    let splitNewTranId = tranId.split('-');
    let splitTranId = _tranId.split('-');

    for (let i in splitTranId) {
        let tranId = splitTranId[i];
        if (!isNaN(tranId)) {
            const results = tranId === splitNewTranId[i];
            if (!results) {
                isValid = false;
                break;
            }
        } else if (tranId !== 'SO' || tranId !== '-P' || tranId !== '-N') {
            isValid = false;
            break;
        }
    }
}
if (!isValid) {
    alert(`'The Order # is Invalid and only accepts -P or -N\nOriginal Order #: ${_tranId}`);
}
return isValid;```


Main part is
```if (!isValid) {
    alert(`'The Order # is Invalid and only accepts -P or -N\nOriginal Order #: ${_tranId}`);
    Returns false after this
}```

I mean code wise it seems like its ok. If false, display the alert and return false. Is something else setting a value? It should put you right back into the box that was invalid.

and chrome is counting the focus changing to the alert

which netsuite counts as an attempt to change the field
