Question

Weird error messages in a formerly calculating Mathcad sheet

I now get error messages (Mathcad 15 M10) in a complex Mathcad sheet with many symbolic numeric expressions that prieviously calculated with no problem.

One is: A numeric term involving the sin function now shows error "this value must be a function but has the form R unitless"

The second occurrs in symbolic evaluations which no longer calculate with the message "pattern match exception"

If I cut and paste the expression to a blank worksheet it evaluates without error

Has any one else seen these error statements? So far technical support has not been able to help other than to suggest updating Mathcad 15 to M20.

It would help if you could post the worksheet so we can see if we see those errors, too.

It looks to me as if you had added or changed something (maybe unintended) in your worksheet which is now responsible for the errors. This would explain why copying the expressions to a new sheet cures the problem.

    Werner I am embarrassed to admit I can't figure out how to attach Mathcad files to my message.

    Click "Use advanced editor" in the upper right corner of the editor window. At the end you then get the opportunity to attach files.

    Another way is to first post normally and then edit that post. This brings up advanced editor. It was demanded by many user that advanced editor should be the default from the very beginning, but to no avail.
