I believe, you need to add the jump-thru behavior to the platform.

If it's not too much trouble, please tell me how to do this? I'm just a newbie, I haven't fully figured out the program yet.

Select the platform sprite that you want to be jump-through-able. Then select "Add/Edit" under "Behaviors" in the properties bar on the left. Select "Add new behavior", then add the "Jump thru" behavior.

Note: This is assuming your character that you want to jump through the platform with has the "platforming" behavior. If your character does not, add platforming to the character.

Hope this helps!
