Hello,

I am new to python and am trying to correct the follow error:

TypeError: sequence item 1: expected string, NoneType found

The error message is referencing line 86 of my code:

ws.cell(row=row, column=1).value = ','.join([str(ino), fn, ln, sdob])


If I'm understanding this correctly, the code is expecting a string, but not finding it.  I'm wondering, what is meant by a "string" and also how I can figure out the problem and correct it.

If anyone could help me understand what the error is and needs to be done to correct it, I think I might be able to fill in the blanks.

Thanks,

Katie
