0 - 1 of 1 tags for bad character format

Hi All,
Not able to figure about the below cause for error. The error is relating to casting. But when i tried cast f12 while inserting the data still i am getting the same error. Please help me to solve this issue.
.logon home/jbhatt,jugal
 .import vartext ',' file=/home/jbhatt/insert.txt
 .quiet on
 .repeat*
