Another A/P question

[Rich Shepard]

   In my personal CoA I created Accounts Payable under Liabilities -> Current
Liabilities.

   When I try to post a vendor bill and select the 'New' drop-down menu, then
navigate to Liabilities -> Current Liabilities -> Accounts Payable and click
'OK' an error box displays telling me the account needs a name. It has a
name (not Phred, but Accounts Payable) but GnuCash does not accept this.
What have I done incorrectly?

TIA,

Rich
