I have some code looking like this:

**\<%= var %\>**

equals less than greater than less or equals greater or equals not equal to is DEFAULT

What I’d expect this to produce for each “var” is:

1. A checkbox with the value params[:search\_param][“var”] equal to 0 if  
unchecked, 1 if checked.
2. A drop down menu that puts a value of 1-7 (default 1) in  
params[:param\_sym][“var”]
3. A text box that takes user input and places in  
params[:param\_value][“var”]

What it actually does is:

1. params[:search\_param] is not created.
2. params[:param\_sym][“var”] is always set to “1”
3. The param value part actually works.

Would anyone mind explaining what I have done wrong?
