Respected Experts

I have this code block

When I run codes then this error appears

The operation + cannot accept the arguments: , [" "], ["56.00"], [" "], [" "]

This is table data where error appears

How to overcome this issue?

Please

@Tariq_Mehmood

Yes sir

The error message contradicts you.

These draggable blocks will protect you against reality.
