With
protected function setMoneyBar(){
$mysidia = Registry::get("mysidia");
$this->moneyBar = new Paragraph;
$this->moneyBar->add(new Comment("You have <span id='cashonhand'>{$mysidia->user->money}</span> {$mysidia->settings->cost}."));
$this->moneyBar->add(new Comment("You have <span id='cashonhand'>{$mysidia->user->money}</span> {$mysidia->settings->cost1}your currency name here"));
