animated circle does not move

Question

what is wrong with my code? why my circle does not move at all?

<svg width="1000" hight="250">
<circle cx="45" cy="45" r="20" fill="green">
<animate attributeName="x" from="0" to="200"
dur="5" fill="freeze" repeatCount="indefinite" />
</circle>
</svg>

Answer 1

Both work!

Answer 2

<svg width="1000" hight="250">
<circle cx="45" cy="45" r="20" fill="green">
<animate attributeName="cx" from="0" to="200"
dur="5" fill="freeze" repeatCount="indefinite" />
</circle>
</svg>

<!-- attributeName should be cx not x... -->

Answer 3

Common error is value of cx-attribute. You both wrote: <circle cx="45" ...... Why "45", if you want the circle move from "0" to "200"?
Correct way is the next:

<circle cx="" cy="45" r="20" fill="green">
<animate attributeName="cx" from="0" to="200" dur="5" fill="freeze" repeatCount="indefinite" />
</circle>
