Syntax to conditionally assign integer or parameter

[Altera_Forum]

Appreciate any help on how to assign an integer or parameter based on a signal, I know the following isn't correct, but i think you can see what I am trying to accomplish. RATE is latter used in an equation with other parameters. Does RATE have to be a parameter for the equation to work?  

  wire low;   RATE = low ? 3 : 4;  ----  if(BCK_DIV >= REF_CLK/(RATE*DATA_WIDTH*CHANNEL_NUM*2)-1 )

I got it figured out -  

 integer SAMPLE_RATE; always @(*)  SAMPLE_RATE <= toneSelect ? 68000 : 48000;
