Crystal reports

hi..
i am using CR 4.5 to create reports for my database package..developed through VB.
during Custom-reports, i gave the option for mutiple lines, so that the field containing more data than specified in the report be printed on next line.
since i am using other fields in the next column, when the multiple lined field prints the data in next line, the hieght of the line extends and the column of data adjacent to it is printed in the next line.
please tell me how to make the column which is not multiple lined to be independent of the column which is mutiple lined.
thanks for the reply...
