Opening balance tax payable

Opening balance tax payable

I have my account opening date as 01/01/15.  I have sales tax payable due 01/31/15 for the last quarter of 2014 and I entered that amount in the sales tax payable field (credit side) of the opening balances.  However, when I try to make a tax payment, Zoho Books is telling me I have no sales tax payable.  How do I fix this?
