Change wronghorizon's FFT design

Hi everyone!

I am a beginner of DSP builder but I belive this design method is more powerfull than what I have studied before. two days ago, follow wronghorizon's posts on this forum, I have learned a lot but when I get into my own FFT blocks, I just confused with my output result.

I use wronghorizon's simulink file myTest.mdl and I want to chang the embedded matlab control funtion into DSP builder based blocks. So I tried but I found my output is not right, Can someont help me find out the bug? Thanks a lot!

FFTfun.mdl is the changed design originated from wronghorizon's design myTest.mdl.
