I ran into this error today Server Errror 131 when trying to enter closing amounts after a blind close out.
We had added a new tender type and we were advised (by ABANCO a credit card company) that a "Display Order" did not need to be set. So I left it blank (or 0) and we blind closed yesterday without problem.
Today we got the Server error 131 and the enter closing amounts screen would not show and tender types except AMEX.
Well solution is / was When entering tender types set a Display order number that is not equal to a tender already set up. our newly added eCheck Sale was display 0 same as AMEX and it stopped up the close out.
I thought I would post this comment because I could not find any references to Server error 131 and had to surf the WWW to find a clue to the solution.
