I'm simply trying to change the text of the button in the "Add to cart" model of the module website_sale.

This is my view:

    <template id="tw_frapolli_website_sale_improvements_options.modal" inherit_id="website_sale_options.modal" active="False" customize_show="True">

<!--> Replace button text "Proceed to Checkout" </!-->    

      <xpath expr="//div[hasclass('modal-footer']" position="replace">
        <div class="modal-footer">
          <a class="btn btn-default a-submit js_goto_shop"><i class="fa fa-chevron-left"/> <span class="hidden-xs">Continue Shopping</span><span class="visible-xs-inline">Continue</span></a>
          <a class="btn btn-primary pull-right a-submit"><i class="fa fa-shopping-cart fa-fw"/> <span class="hidden-xs">Get Quote</span><span class="visible-xs-inline">Get Quote</span></a>
        </div>
      </xpath>
                    
   </template>

However, I always receive the following error message:

 File "/usr/lib/python3/dist-packages/odoo/tools/convert.py", line 255, in _test_xml_id assert modcnt == 1, """The ID "%s" refers to an uninstalled module""" % (xml_id,) odoo.tools.convert.ParseError: "The ID "tw_frapolli_website_sale_improvements_options.modal" refers to an uninstalled module" while parsing None:16, near <data inherit_id="website_sale_options.modal" active="False" customize_show="True">
