Problems Using Automate to Batch Resize Images

Hi 

This is potentially quite a basic question but I am fairly new to photoshop and am running into problems using the Automate function in Photoshop. 

I created an action to resize the image and have tested it to check it works on a single file but then when I try and change file size using the automate function I get a pop up saying image size is not available, save is not available, close is not available.

Does anyone know what I am doing wrong ? Thank you in advance
