Alert when checking a radio button

[Wissam5FBB]

In a form I created, I have a Radio button RB1.  If the RB1 is selected, I'd like to have an alert message ('too high') if the calculation in another Text Box (TB) is >1000.

Thanks

Use a mouse-up action script in the radio button field:

if (this.getField("TB").value >1000) {app.alert("too high");}

Thank you very much, it works!
