Tried various fields with alphabetic input. I either received an error like: “Error in if (Lm50 == 0) Lm50 <- NULL: missing value where TRUE/FALSE needed”; or the run check found no errors.
Only allow numeric values for inputs (where appropriate), and give an error message such as : Error message should read “Numeric values required for this field”
