I am not able to create a pivot table - error message is appearing saying
that pivot table field name is not valid. it also, says, to create a pivot
table, you must use data that is organised as a list with labeled columns, if
you are changing the name of a pivot table field, you must type a a new name
for the field. I dont know where is the issue - my data has all the colmuns
labled. i am stuck up.
