Format currency withHTML

HSMorales

I have a text box with Dynamic Text HTML "The amount you owe is : <VALUE-OF>row._outer["INV_TOTAL"]</VALUE-OF>."

where INV_TOTAL is a currency value.

What is displaying is "The amount you owe is : 166.6."

I would like it to display "The amount you owe is : $166.60."

What syntax do I need to get it to format INV_TOTAL as currrency ??

Thanks
