Yes you do. See my other reply with the code.

Title variable has STRING type (so it has no "interval" concept).
On the other hand Interval(2) would return name of selected timeframe
provided it is used INSIDE timeframeset block.
You did not do that in your code. Again, see my other response for
code how to do that properly
