Hello Paulo,

you have some options to do this. 

Simple way is to add an onChange and then in the that action, do the assign with Length( Message ), and then refresh the expression as shown bellow.



This way, the number will update as soon as you stop typing.

If you want to update that number everytime you type a letter, you need to create an hidden link ( style = display:none; ) this link will point ou to the same action above, name the link with something like hiddenLink. Go to text area extended properties and add onkeyup property and in the value "osjs('#"+hiddenLink.Id+"').click();" this will trigger the refresh action everytime you type.

These should do the job, let us know!

regards,
Miguel
