You will have to hard code the currency amount into the script.
In the first line, create 2 text fields, Text1 and Text2. Use this as the custom calculation script for Text
this.getField("Text2").value = this.getField("Text1").value * 100;
The second pair of text fields would be:
this.getField("Text4").value = this.getField("Text3").value * 50;
etc.
