Hi
I’m new to this forum and new to AS3 so please igoner my stupidness. I’m trying to build a photo gallery and have almost got there but I am stuck with one error that I can’t get rid of or find the answer too, which is:
ReferenceError: Error #1069: Property picCaption not found on Thumbnail and there is no default value.
at photoGallery_fla::MainTimeline/onClickHorizontal()
The error happens on the following line which is in the last function of the second block of code below:
photoDescVertical.text = event.currentTarget.picCaption;
When I debug and put a break point on the line and in the veriable window expand event.currentTarget picCaption is there and has the text I expect, so why am I getting the error?
This is hopefuly all the code to help me out!
