How Change "space" to "," . For example, 3 525 USD ----> 3,525 USD.


I'm grateful to you for help in this area. (Very urgent I need this module)

What you did, changes only how records are written in database. This is only affected to database, when you install the module. But I think, with this solution you might get some errors when module would try to save the record into database, because author had some different idea at module creation.

But you would probably like to change the outcome in screen. Therefore you have to search in templates of that module.You have to change only the output to the screen. There you can make changes which will satisfy your needs and will not mix with code.
