What Innertube is needed for my Schwinn Men's Volare 1200 Bike, 700c, Grey I thought I purchased the right size. Two times I have gotten this wrong. 
Can any body point me in the right direction? i was hoping to find some on Amazon. And it is so confusing...

Bike tyre sizing is a horrible mess.

Your wheel is a 700c - that means the diameter of the whole wheel.  you have to get a tube that is a 700.

The second number on the tube relates to the width of the tyre, and is often given as a range.   Racing tyres are 18-23 mm, the next band is often 25-35, 

So you need to read the writing on the sidewall of your tyre and see if its a 700-28c or similar.

It doesn't matter what width of tyre the bike came with, what matters is the width of tyre on the bike now.

Refer to How are tire sizes measured? for more info.
