Issue with populating the parameters

Hi,
I am using crystal report 11.My dynamic parameter displays company codes (4 digits).While populating, company codes are displayed as seperated with commas.But i need to display full 4 digits without commas.
For example:- Database value : 2345 Dynamic parameter displays as 2,345. How to avoid this issue ?Try to use formula having the code totext(field).
or goto format field and dormat it not to have commas
