Columns and Rows

I am trying to get a filed in my form to use both columns. I am using "2cols2lines" layout. I have tried changing the columns and rows settings but they seem to not do anything what so ever. I need to be able to have a question strecth from one side of my page to the other, but only this one question. I assume thats what the col, rows field settings is for, if not it should be. Please advise.

The Columns and Rows setting in the custom field is only used for textare acustom field . It is used to define the width and height of the textarea . If you know abit about HTML, the code for the textarea will be :
Hope it is clear !

Thanks,
