Differenct between paged query and query

Hello All
Can someone help with this? Trying to load image from my database.
non page query: works great.
'/uploads/images/products/'+category_id+'/'+image

Paged query.does not work.
'uploads/images/products/'+serverconnect_paged.data.query.data[0].category_id/serverconnect_paged.data.query.data[0].image

Thanks Joe

I want you to look at this expression very carefully, look at the last slash (/), do you notice any problem?

If you don't notice the problem, look at the expression that works, compare the same last slash (/):

What's the difference?

Hello Apple thanks for the help.
'uploads/images/products/'+serverconnect_paged.data.query.data[0].category_id+'/'+serverconnect_paged.data.query.data[0].image this one works. When I pulled the data in that is what it pulled in I had to add the +' and '+ to get it to work.
