Cannot import multiple nodes in feeds module using csv files Im trying to import these files into nodes in my drupal 7 site 



i used the no header and i mapped the columns into numbers (0,1,2. ..)

but i end up only getting only 1 node. 

The alert says "created 1 node, updated 19 nodes" how come?
You file shows 20 rows. From your description, I bet that the GUID has been the same for each import, and you have actually created one node 20 times. (Created once then updated 19 times.) You need to define a unique field in each record, with a corresponding unique field in your node (eg guid). Then feeds will map that field to determine which nodes to create (no nodes with matching unique field) or to update (node has a matching field).

Try using the Title field as unique instead of guid.
