dot and comma to separate dollar and cents

Some colleagues in US or other countries all over the world capture data via a form into Smartsheet. Sometimes cents are neeeded so the dot will be used to separate the dollar from the cent.

My account is in Germany and the the Germans use the comma for separation not the dot.

All data run into a failure and I have to delete the dot and to enter a comma.

Within the form its only possible to proof for an amount not how much digits have to be captured on the right side of the comma.

How can I improve this.

Thanks for your comments
