Load and With with local variable

Question

Hi , 
 I know it could be an silly question but as i am learner so for me need to understand Why ?? 
 Why with is not accepting load variable and throwing Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error : Cannot add incompatible operands of type Number (Integer) and type Null. 
 load( local!c:10, 
 with( local!a:10, local!b:20, local!a+local!b+local!c) ) 
 
 But if we do reverse its working. 
 
 load( 
 with( local!c:10, local!a:10, local!b:20, local!a+local!b+local!c) ) 
 Could not display interface. Please check definition and inputs. Interface Definition: Not a valid component. Received: 40

Hi Saurav, 
 
Try it like this .Since you have not given a valid component you are getting error 
 
load( 
local!c:10, 
 
with( 
 
local!a:10, local!b:20, 
 
a!integerField( 
 value: local!a+local!b+local!c 
) 
) 
)
