WILLISTON (AP) - A software problem led to an error in early vote totals on moving the state Farmers Union headquarters, though it did not change the result, the group's president says.

Farmers Union Mutual Insurance members attending the state convention in Williston on Saturday voted 5,384 to move the headquarters from Jamestown to the Bismarck-Mandan area and 4,949 against it, President Robert Carlson said Sunday. That was short of the two-thirds majority needed to pass.

Carlson had reported the vote Saturday as 1,600 against the move and 1,100 in favor of it. He said an error was discovered later in the day.

"The software that we had for the voting had a programming error, in that it didn't account for the maximum number of votes that some delegates were carrying," Carlson said Sunday.

"Our auditor was on the highway. We said, 'We think there's an error.' He came back and looked at the data. The error was corrected."

Delegates to the convention approved a resolution to continue studying the headquarters move, said Carlson, who was re-elected as the state president.

More than 600 Farmers Union delegates attended the convention, he said.
