Change the default tax type in sale order

[addady2]

Hi,

I would like to change the default tax type when creating new in sale order, invoice etc.

I modify:
Smarty/templates/Inventory/ProductDetailsEditView.tpl

diff

Code:

<select class="small" id="taxtype" name="taxtype" onchange="decideTaxDiv(); calcTotal();">
-                       <OPTION value="individual" {$individual_selected}>{$APP.LBL_INDIVIDUAL}</OPTION>
                        <OPTION value="group" {$group_selected}>{$APP.LBL_GROUP}</OPTION>
+                       <OPTION value="individual" {$individual_selected}>{$APP.LBL_INDIVIDUAL}</OPTION>
                </select>

and delete
./Smarty/templates_c/25.............df_0.file.ProductDetailsEditView.tpl.php

But it didn't help.
Any idea?
