Unhappy Barlow focus

Hi All

I'm a newbie to this site and glad to have joined. I'm also very new to this wonderful, interesting world of astronomy. To see if my interest would turn into a hobby, I purchased a Skywatcher Heritage 76mm (miniDOB) beginners telescope which came with 2 eyepieces (SR4mm and H20mm) and have been using it to find my way around the night sky, which has been great.

To enhance this, I purchased a ProStar 2X Achro Barlow but have been unable to get anything in focus once I use it. For example, an object I can focus on with both eyepieces suddenly cannot be focused with the Barlow and either eyepiece.

Can somebody please explain what's wrong without getting too technical in the first instance ?

Any help would be greatly appreciated !

Many thanks
