Hi Bill,
Another aspect that all have missed is that Jupiter rotates - even if your telescope is able, the red spot isn't always facing earth and you may be looking at the wrong time !
The rotation period is less than 10 hours so on many nights it's possible to see it, a couple of hours either side of its meridian times

As others have noted it is a real challenge to see it in a scope as small as yours though I'd say not impossible, once you can see the brighter bands.
