new version upload problem

I uploaded the new version of RF & Microwave Toolbox (1.01) but the old one remains active.
When I try to upload for the second time I get the message;

The APK file contains the version 1.01 (code 133); previously you uploaded version 1.01 (code 133). The version contained in the APK file must be higher than the current version.

You need to update the version number in your manifest.xml file. In order to upload a new version to the market, it must be at least one number higher. Edit the manifest lines of your manifest.xml file and rebuild your .apk. Below is an example.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
android:installLocation="preferExternal"
package="xdebugx.OTC"
android:versionCode="13" <----- increase this number with each new version!
android:versionName="1.1.1">
