decimals on form

Good day All

I have a form to input data into a table1. On the form I have a combo box to read from a next table exchange rate to input into the table1. Field in Tablet for the exchange rate is set to Field size double, Format currency, and decimals 6. I am unable to set the field size on the form to read the 6 decimals. The combo box is set to Currency decimal 6. I tried General Number and it still only shows only one decimal.

Would someone please tell me what I am doing wrng.



Thanks



Cristina
