Read this and try again.

send some block images and output

Vague guess!
Your button is either disabled or there is no on-click event in the blocks

I unlist this until we get more information.

you have to clear cache in your computer or you have to refresh laptop or pc if this also does,t work then you have to close the browser and refresh it and try again it cache problem
