I want to merge these two buttons into one button:

First button code:

<input class='contact-form-button soracustomform-ok' type='button' value='Confirm Order'/>
<a class='simpleCart_checkout' href='javascript:;'><input class='contact-form-button contact-form-button-submit disabled' disabled='true' id='ContactForm1_contact-form-submit' type='button' value='Place Order'/></a>

Second button code:

<input class='contact-form-button soracustomform-ok' type='button' value='Confirm Order'/>
<a class='simpleCart_checkout' href='javascript:;'><input class='contact-form-button contact-form-button-submit disabled' disabled='true' id='ContactForm1_contact-form-submit' type='button' value='Place Order'/></a>

Check this demo template here: sorashop-soratemplates.blogspot.com/p/checkout.html

Try to place an order and you will see two buttons on the checkout page first button for confirmation and the second for place the order, I want to merge them in just one button, so when someone want to place an order he will just need to click on 1 button to confirm and place the order at the same time without click on confirm then place.

Thank you!
