Help in Error at logical operator bock and constant to compare block

I build my model to detect ball in video input, when i trying to running the model, i received error ''Error in port widths or dimensions. Invalid dimension has been specified for input port 1 of 'model2/Subsystem1/Logical Operator'.'' at logical operator block. Also another error ''Error in port widths or dimensions. Output port 1 of 'model2/Subsystem1/Compare To Constant' is a [50x1] matrix.'' at compare To constant block.

Please need any one help me to solve this error

You are comparing 1 signal with 50 signals. Use a demux which has 50 outputs and compare one by one
