python – The object & # 39; Ui_Form & # 39; does not have attribute "CULOMN_5"

I've changed self.CULOMN_5 with self.ROW but still the same error if everything is on CULOMN_5

I continue to get the object "Ui_Form & # 39; which does not have the attribute "CULOMN_5"

def double_table (self):
for currentItem in self.tableWidget.selectedItems ():
self.CULOMN_5 = currentItem.column ()
self.ROW_5 = currentItem.row ()
#if you ckick on the column (i, 4) i want to get the result
if (self.CULOMN_5 == 4):
self.l = self.tableWidget.item (self.ROW_5,2)
self.w = self.tableWidget.item (self.ROW_5,3)
self.l = self.l.text ()
self.w = self.w.text ()
## print (self.l, 'self.w,', type (self.w), ', type (self. l))
#Multiplication of two columns to the same line
if (self.l! = & # 39; and self.l! = None and self.w! = & # 39; and self.w! = None):
self.m = float (self.l) * float (self.w)
self.tableWidget.setItem (self.ROW_5,4, QTableWidgetItem (str (self.m)))
other:
self.tableWidget.setItem (self.ROW_5,4, QTableWidgetItem ("Error"))
other:
pass

I want to multiply two columns in the same row and show the result on the last column of this row
