Array[0] has no properties

[neridaj]

Hello,

 

I have a multidim array that is generated with php and I don't understand why/how to fix these errors:

 

Error: atrarr[0] has no properties

Error: atrarr[imgname] has no properties

 

I put an alert in the change_slide() function and it says the var imgname is undefined however, upon viewing the php output the var imgname is defined.

 

Here is the php output:
