Try typing this bit in the command window:
>> '(pname,fname)'
ans =
'(pname,fname)'
So your path is a string named (pname,fname) - not your actual path string.
In addition, your range syntax is bad. You have to specify endpoints as specific cell numbers... Although, if you write your entire table, you dont even need to specify end points - just give the start point.
If you dont want to write the entire table, specify which part of the table you want to write, instead of using the spreadsheet corners as constraints, its much more neat.
Here:
writetable(T1,[pname,fname],'Sheet',1,'Range','A2');
writetable(T2,[pname,fname],'Sheet',2,'Range','A2');
