waveform contains no values

[santoshksv]

i am doing a project to calculate BER of QAM modulation, i am obtaining all the symbol outputs but at the MT calculate BER it is showing the following error "waveform contains no values".

can anyone say where is the error and what to do?

i am posting the VI and screenshots of the error..

Hi santosh,

did you try to debug your VI?

Did you use probes to test all waveform wires?

Did you use breakpoints or highlight execution to find the function/subVI giving that empty waveform or error message?
