Sorry , it didn't work ..
Since I have tried the solution you provided , it didn't change the Pow2 and Powfee at all . I have made a compelete New insert page for trying the things you tell me . But ,feel pity that didn't work . Again ,I upload the insert.php and the database structure and data for you so that you can simply check the checkbox and insert and will see that PolItem data table with the same value of pow2 and powfee column .( if you used the data I provide , the Pow2 coumn value will be *all* 100 and Powfee column value will be *all* 1000 ) So, there must be something wrong with it , but I don't have any clue about it.
I don't know where the problem is ,and supposed maybe this is a bug in MRT server behavior .
What I upload is everything in my test site , and You can See What I am saying .
Any suggestion will be appreciate.
