Post a screen shot, including the Layers panel.
Confirm the layer order and object order.
If they are both okay, look in the Effects panel to see if an Effect has been applied. If so, delete the Effect.
You've probably got a text wrap applied.
Object > Text Frame Options, tick Ignore Text Wrap
thanks for the idea; i tried but my text still won't show
I agree with everything you said, and yet—it shows overset text. Let's keep looking. Something is keeping it from showing.
1. Make the text frame bigger
2. Go to Edit > Edit in Story Editor
3. Click the Paragraph settings in the Control panel to look for spacing settings
4. Turn on Hidden Characters
Earlier today, I selected "ignore text wrap" and ok-ed the window to close it at your suggestion, but I still didn't see my text. I re-did the process just now, and suddenly it worked. My order of operations earlier was evidently off in some way. Problem solved & thanks.
I somehow hadn't gotten the text wrap ignored earlier. Thought I did, but obviously my clicking order was off somehow. I just re-tried and it worked...
