I've tried this multiple times, using multiple files and looking at numerous threads to no avail.
I only get half the animation, I want each letter to come in individually at different times so I used the "Ramp Up" feature of a Range Selector.
Please help me ASAP because this has been bothering me for a long time.
When using a Ramp Up or Ramp Down selector shape you'll generally want to animate the Offset instead of the Start and End values.
For example, if your start and end values are 0% and 100% respectively then you'd animate your Offset from -100% to 100%. If your start and end are 0% and 50% then you'd animate your Offset from -50% to 100%.
The Offset is what actually slides the ramp through the characters. The Start and End values only define the width of the ramp.
