'line0: indicator 'specify' is not unique'

[piyusha]

When i am importing the file, lot of lines of data appear in the 'indicator' header stating 'line0: indicator 'specify' is not unique' and many such lines below
Also, when I select 'active data file' there is nothing which shows on the left tab of yellow 'indicator'
Where do you think, is the error coming from.?
i have even tried changing my variables from string to numbers
the one attached below is with string values

line0 is the first line of your data file where you should have the variable names. These do not seem to be unique. You need a unique name for each variable.
