Email Notification Condition

I’m setting up a notification in ERPNext and want it to trigger only if a specific field in the document has a value.

For example, I have a custom field called first_month_reminder_1, and I set the condition in the notification as doc.first_month_reminder_1 .Below is my condition screenshot .

My question is ====> will this condition work to send the notification only when the first_month_reminder_1 field has a value?

Because some cases this field (first_month_reminder_1) has no Value .

Same as Trigger only first_month_reminder_1 and doc.send_only have value .here send_only is a check box field .Below is my Screenshot of Notification Condition .

Here this work Currectly Because I’ve noticed that in the notification setup, the condition (Logical AND) doesn’t have any color change in the UI. Does this mean the condition is invalid, or will it still work as expected?

Please Help
