but when i'm updating the table it show me the error message "Data type conversion error"
could anyone help me?

Have you set Option Explicit in your code module. If not then do so. It will then trap any errors caused by using an undeclared variable.

Try changing this line

coupon_bbtxt = Format(listbuyback.Column(5), "0.00000%")

to

Me!coupon_bbtxt = Format(listbuyback.Column(5), "0.00000%")

I have change my line to :
Me!coupon_bbtxt = Format(daftarbuyback.Column(5), "0.00000%")
but still get the error message "Data type conversion error"......
but when i'm removing the "format" and the "0.00000%" the code working just fine....

When you use format it is coercing it to be a STRING (TEXT) instead of a number.

You can't include the % sign when putting it back to a number field.

my first intention in using "format" is because if i just wrote this code:.
coupon_bbtxt = listbuyback.Column(5)
and suppose the listbuyback in column(5) has the value of 15,50%
then the coupon_bbtxt will return the value "0,155" although i have change the format to percent and decimal to 5 of in the coupon_bbtxt's property

And since i want the textbox to display the value with percent (similar tothe listbox), i use "format" to display the percent....
so is there any suggestion?

ps: in the listbox the column(5) keep displaying the percent value with 2 decimal places although in the table that the listbox get the value,the value is a percent with 5 decimal places behind zero?

thx
