To register data from userform

Hi,

I have a code as you can see in the attached file. I have tryed to modify this to work as I want, but I failed and need help.
When opening the worksheet, there is only one command button. This will open a userform where I want to save the data from row 18. next time in row 19.

I now you people in here are superb, so hopefully somebody will help me solv this.

Thanks in advance.


Best regards
Øystein
