Take a look at the description of the "round" function in the Metatalk Reference stack. It explains how to tell MC which digit to round on.

I think making the field clear whenever the user clicks in it it is not nice. If the user want to select some characters, the field clears.

Tim, what you are trying to do is kind of against expectations but ... Imagine you entered the wrong number in one of the fields and you want to select some or all of it in order to delete/change it. Set the lockText of the fields to true when you click the Convert button; that would enable the fields to accept a mouseUp. In that mouseUp you can put empty into the 2 fields and set the lockText of them to false. > >on selectionChanged #or mouseUp put empty into field "Degrees C" put empty into field "Degrees F" #I want it to clear both fields select field "Degrees C"end selectionChanged #or mouseUp > >My plan is that you click on either field and it clears both.
