I work for an international company. We have a standard form that is required to be filled in for salary increment requests.

Currently this is a restricted form, where only specific fields can be edited.

The salary field has a Number type, with Unlimited length and the format is

$#,##0;($#,##0)

This has the effect of converting whatever currency symbol is input into the dollar symbol.

Is there a way of editing this so that a currency symbol is mandated, but that can be ANY currency symbol, not just the dollar?
