OB2

That’s because the MAC variable is not being replaced correctly as you can see, you have something wrong. Are you sure it’s not supposed to be <input.CODE> instead of <CODE>? Make sure you are also using the interpolated string setting (dark green background)

i try input but same

You have to click on the T next to the box until it turns dark green. You have to do this process for EVERY box where you want to use variables like <this>

i did but

That means the CODE variable does not exist in your input data. Are you sure it’s not <input.MAC>? You have to check the log and see how the input data is split into variables.

thanks for your help
I fix it.
