In the interface. I am getting error message for the below piece of code. 

Error message :

Expression evaluation error in rule 'sshs_startformquestions' at function a!cardLayout [line 48]: Cannot compare incompatible operands of type Null and type Number (Integer).

Line: showWhen: {
local!selected1 = 2
}

It would be great if someone can help.

    There are two Possibilities of why you see the error,

    1. Either your Local variable local!selected1 has no value,

    if it is giving this message as soon as you write the code, may be you can do a null check for your showWhen. Lets say if-isnullorempty-{}-your condition.

    2. It has a non integer value. If you are fetching or indexing it from somewhere else, may be you can wrap it in the tointeger() function.

    Here , local!selected1 is having a null value so its giving the error message. you can use tointeger(local!selected1) = 2 and it will not give the error message as it will change the variable into the required format of integer.

      Thanks for your reply. I have 3 local variables defined. It would be great if you can help here on how to use the isnullorempty condition
      showWhen: and(
      local!selected1 =1,
      local!selected2=2
      )
