Image sampler fail to have output data

Sorry guys if this problem seems easy to you, but I’m a beginner of grasshopper. So I’m trying the component Image Sampler and it says that it fail to create output

data. Is there anyone could help? Thanks.

Can you upload that part of the file? I cannot see an obvious mistake anywhere. (302.8 KB)

Your image sampler is Disabled. Right click on it to get the context menu and click on the Enabled item to switch it back on.

I don’t blame you for being confused, there is no good visual feedback for this in the case of the Image sampler object.

oh right, I totally forgot that I disabled it. Really appreciate your help and fast response!
