How do I create a currency counter?

Or rather, a Box that says CURRENCY: (amount of currency) that displays at all times

At some points in this game, you collect, let's just call them coins. The amount of coins collected will be stored in a global variable, but how do I get the amount of coins to show up in the currency Box?

one way would be to place a text object over the box and then ad an event "each tick" or "every x seconds" set text to "$" & GLOBALVARIABLE

Thank you!
