I have made simple modifications (adding text, hyperlinks and customer info using tokens) to some System Workflow templates, but now I want to try adding an if/else statement so that the off-line contribution 'receipt' becomes a refund notification if the contribution amount is negative.
 
What "language" are these written in and where can I learn the syntax etc.  I thought it might be php, but it doesn't look like the php I find  at w3school. (no programming experience really - I can tinker successfully with mssql and a little bit of html and CSS when I have to, but that's all)

I think I might need to add something like the red lines to the existing blue lines of code but I'm not sure if I can nest if/else statements or not , and I not even sure if {if $formValues.total_amount neg} is correct way to identify negative contributions.

{if $formValues.total_amount neg}
<t> You refund has been processed as requested. </t>
else

 {if $formValues.receipt_text}
     <p>{$formValues.receipt_text|htmlize}</p>
    {else}
     <p>{ts}Thanks for your support.{/ts}</p>
    {/if}
     
    {/if}

It should be something like

{if $formValues.total_amount neg}
     <t> You refund has been processed as requested. </t>
{else}

 {if $formValues.receipt_text}
     <p>{$formValues.receipt_text|htmlize}</p>
    {else}
     <p>{ts}Thanks for your support.{/ts}</p>
 {/if}
     
{/if}
