Direct sales invoice quantity entry changes [solved]

Hi,

I have FA (2.3.24) installed on a webserver running LAMP.
The users use Firefox (latest version) on Windows 7.

When we start a direct invoice and enter in the field for quantity the amount of 3,
hit tab then 30 is in the field.

Does anyone have an idea how to solve this?

Yes, i found it.

If you put the article in "foreign item codes" and you put the quantity on 10 then this is what you get.
changed it to 1 and all is fine now.

Kind regards,
Jan
