Creating Withholding tax Entries


I have a problem again, can anyone help me how to create entries for withholding tax? Here is the situation. In gen journal in the button withholding tax group located in the lower part of the journal form I specify the expanded withholding tax, but when I am inserting an amount I encounter this message in info log " This line has withholding tax. To change the amount to pay, enter corrections in Open transaction editing. What am I supposed to do with that?

Please help me to understand the process. Thank you very much in advance

here is my transaction:

Rent expense - DR

Input tax - DR

Withholding tax -CR

Cash in Bank- Cr
