Money: dollars and cents

I have nine images on the screen.  Each image has a dollar amount associated with it as a variable.  As the user clicks on each item, a cash register displays the ongoing tally.  The user may click one image or all the images or click on an image multiple times.  That all works fine... almost.  Can Storyline display the decimal point and cents?  At times the final tally is "$176.30" but storyline displays "$176.3"  Also, "$140.00" shows as "$140"  I need the cents to show as well.  And is there a way to add a comma for numbers over "$1,000.00"  Storyline displays it as "$1000.00"

Anyone have their 2 cents to offer?

Thanks,
