QTP 11.52---Type mismatch error

[srinijg20]

Hi,

Im getting type mismatch error while calling a function

eg

Code:

function add(a,b)
sum=a+b
msgbox sum
end function
call add(10,20)

the error is: Type mismatch:add

note:i didn come across this error in UFT 11.5 but UFT 11.52 is showing this error
