About getting key frame values

Hello, just a few minutes of your time. Is that what it says? After I wrote it this way, when I run AEGP_GetNewKeyframeValue inside AE it says: no current context. the Description Failed to obtain the key frame value is then displayed. Here is the code I wrote, I don't know whether it is correct or not. Could you take a look for me, please? Thank you very much.
