Error occurred when converting simulink block to HDL code

In my Simulink block i used a constant to multiply. When i convert the block to HDL code i get an error as "Attempt to reference field of non-structure array" but when i removed the constant i am able to create HDL code. How can i over come this error?

Try swapping out the multiply block for a gain block, since you are multiplying by a constant. Other than that, you might want to examine the Constant block: what is its data type? Is the value compatible with the data type? Are any of the other mask fields inconsistent or inappropriate for HDL code generation?
