Error message for 1099B Worksheet

For all 3 of my 1099B entries, TT says "Cost or Adjusted Basis (Positive Amounts Only) does not match the value on the Capital Gain (Loss) Adjustment Worksheet. Leave this value blank when using the Capital Gain (Loss) Adjustment Worksheet." I get an analogous error message for all my "Sale Price" entries. First, the values absolutely do match. Second, if I leave them blank as the TT error directs me to, then I receive a new set of errors telling me to fill them in. Please advise...
