Hi,

Using PB2019 SQLAnywhere 16

I want to create a computed field on a grid datawindow. I am trying to use isnull()

so on the computed field i wrote isnull(amount)

I get the following error 

SQLSTATE = 37000

[Sybase][ODBC Driver][SQL Anywhere]Wrong number of parameters to function 'isnull'

I have attached a pic of the data selection.

As always thanks in advance for your help it is much appreciated
