now when everi selected the radiou button labled rate 1 rate 2 raet 3 it makes a new row in the db - what i want is that it do not make a new row but it add the
rating to the excisting coloum from which the image is coming from.if the image-url is coming from the karen record(see above table) then it should add the rating to
that row (1+1=2 or 2+5=8) it should not make a new row but when i try it makes a new row that i do not want
