How to Initialise variables for simulink's matlab function block?

I using matlab R2010b matlab. In simulink I am not able to initialize the variables I want to use in 'matlab function block, I also used Preloadfcn callback as: set_param('mymodel/Test', 'Fish_rugg', loadvar);

my loadvar.m contains: time =0; I am using a matlab function block where I am updating value of variable 'time'.Now when I open my model 'Fish_rugg' and run it.Although my time is being initialised and also showing in workspace but it is showing error 'undefined variable 'time' first usage of variable define its class.I am not able to understand what is the problem in matlab function block that it is not using workspace variable.

Any help in this context will be greatly appreciable.
