error when refreshing pivot table
 

Hey there, when I went to refresh my pivot table for the month it said
"pivotable field name is not valid" I tried to redraw my table perameters and
it didn't help. It won't let me get to the screen to reselect the column
headings. I copied and pasted the page to a new file and tried to do the
table from scratch and it still didn't work.

PLEASE HELP ME!!!
