Question: I'm constructing an area with selectable buttons that transition and appear every 10 frames. During these 10 frame transition periods I don't want the buttons to be selectable and if possible to disable the rollover.

I've tried creating an If statement on the addEventListener so that it only works when currentFrame is 11,21,31 etc but this didn't work. I then also tried the same principal on the function to which the Event Listener relates but still no success.

Does anyone have any ideas?

Answer: 
Try to put this in your CSS file.

```css
td {
  text-align: center;
  vertical-align: middle;
}

```
`<td align="center"valign="center">textgoeshere</td>`
