Problem with ''Add attribute''

Hi Nick

I have a problem with adding an attribute to an object in Maya. Unfortunately it doesn’t deem to work for me.
What I do is: click on the object / from properties – add attribute – name-- leave it on the float option / ok

Then I manually change a property for example ‘’rotation’’ or ‘’x-y-z translation’’.

Then from the script editor I copy and paste the commands as you advised.

When I try to test it does not work.

Why do you think this happens? Is it something I do wrong? I remember yesterday you have tried as well on my pc and it did not work either.

Any advise please?

Many thanks

Maria
