app.alert still shows after age is entered.

[yeungyam]

Once a checkbox have been checked, an alert message will appear if the age field is empty. 

Click "OK", then setFocus on age field.

After I enter the age and click out of the age box, the message still appears another time, as if the value hasn't been committed yet.

How do I show the message only once?

if (getField("Run").value == "1")
{

if (this.getField("MaxHR").value == "")

app.alert("Please enter patient's age or Date of Birth!",3);

getField("age").setFocus();

}

}

You are using two different fields, "MaxHR" and "age". Even if you fill "age" field alert will pop as long as "MaxHR" is empty. Change "MaxHR" to "age".

How silly of me.
