function depending on two variables

Hi there,
I want create a pressure field in which the pressure is decreasing in both the x and y direction (or basically increasing with depth).
I have written it as 10^5+(200-x)*(0.3*10^5)/200+9.81*910^3)*(50-y).
I get the error "wrong number of function arguments".
Does anyone know if it is even possible to solve a multivariable linear function in comsol? And if yes, any suggestions on what might be giving the error?
kind regards,
M.Deen

in here: "10^5+(200-x)*(0.3*10^5)/200+9.81*910^3)*(50-y)" you are missing "(" somewhere.

It is possible to declare a multivariable function.
Did you declare both x,y in the argument section of the function ? from the error it looks like you have just declared a single argument. If that is not the case, please provide more information about the error, expression, arguments you are using.
Good Luck.
