A valid Risk Detective result worksheet must be active first.

This command requires that the active worksheet be the product of a prior Risk Detective analysis.

Aliased bases must be single cells.

When using an aliased range name in the base column, this range name must refer to a single cell, not a range of multiple cells.

Ambiguous Decision header definition. Avoid multiple definitions.
Ambiguous Input header definition. Avoid multiple definitions.

The Decision Table allows you to define multiple alternatives, and automatically repeat the analysis for each alternative, generating a comparison. If you only have 1 alternative to analyze, you do not need to use a Decision Table.

Decision table requires Number and/or Name header.

A Decision Table header requires at least a 'Number' or 'Name' entry (or both).

Decisions can appear only once in the Tree Table Decision column.

In the Tree Table Decision column, define each alternative's starting tree node only once.

Error with user calculation routine.

Suggest debugging this interface with a simple beep command to make sure that control is passed from Risk Detective to your routine effectively.

From must be less than To for sensitivity chart.

Your output numbers selected in making a chart must be arranged such that the From number is less than or equal to the To number.

Incomplete multiple variation at end of Input Table. Check for too many Ands.

The last line of any joint variation should NOT have anything in the And column. Risk Detective has reached the bottom of the Input Table, and is expecting to find another row since an And entry was last found.

Input table must have as many PValue as Value headers.

When defining more than 3 branches for Scenario Analysis, you must add a Value and Pvalue column to the Input Table for each branch beyond 3. For instance, if a node has 5 branches, you must add 2 Value columns, and 2 Pvalue columns.

Input Table needs more rows than just the header.

When defining the Input Table, highlight the entire table, not just the header row, then use the Define Input Table command.

When defining the Output Table, highlight the entire table, not just the header row, then use the Define Output Table command.

Output table requires Description header.
Output table requires Value header.

At a minimum, the Output Table requires the headers of 'Description' and 'Value'.

Output Table values must be numbers.

Risk Detective can only analyze and compare numeric results. Errors or text results in the Output Table's Value column will generate this message. Check your model and make sure all calculations result in valid numbers.

Overall probability must sum to 1.

The sum of probabilities for all branches of a node must equal 1.

Probabilities did not sum to 1 during EVPC/EVPI Calculation

Most likely you have an error in your calculated probabilities. Recheck them.
