This error occurs when action parameter is not specified for a menu item.
%s - Menu name.
Add the appropriate action parameter.
Example
[#Menu: Gateway of Tally]
Add: item: "MyReport" :Display
In the above example, the action Display for menu item does not have its parameter. Hence the message error T0036:Menu Item MyReport' does not have an action parameter.
This code is corrected by adding the appropriate action parameter.
[#Menu: Gateway of Tally]
Add: item: "MyReport" :Display : MyReport
[Report: MyReport]
Use: Balance Sheet
