playframework - How to declare and access local variables in scala template in play framework? -


i have code in scala template like:

@for(col <- list.range(0,12)) {     <td>         @if(col % 2 == 0) {             @{ val letter = somemap(col) }             <div class="z@(letter)@(letter)s"></div>         }     </td> }

but compile error: value letter not found. how can declare variables , able access later in markup above?

actually have never seen @if nor have tried playframework. if think is, seems when try ask letter it's out of scope. happens if re-arrange brackets follows?

@for(col <- list.range(0,12)) {   <td>     @if(col % 2 == 0) {       @{val letter = somemap(col)         <div class="z@(letter)@(letter)s"></div>       }     }   </td> }
