Different GMM

[bp_1009]

When I use wizard dynamic panel data to run GMM method, after finishing all steps, there is a message " insufficient number of observations".
My sample includes 30 countries during period from 2000 to 2012, it means there is 390 observations in my sample.
Please tell me why there is the message like this.
I attach my data

For most dynamic estimation, what matters is the number of observations per-cross-section, not the total number of observations.
