Help with building a logic based on array of texts

[fahmed-2]

Hello,

I have a Mathcad sheet which I am working on to find the factor of safety for block walls. The sheet will calculate and spit out a text "Stable", "Unstable" based on a comparison , which I have provided in the logic. What I request to have is a Mathcad prompt, that checks the array FS_OT to see how many "UNstable" are there. If so, it should send out a message saying "UnStable" and tell me at which level of the layer of blocks are unstable. Please help on this as I am not that pro level. My Mathcad version is Prime 10. This is not an error issue so no screenshots were provided.

Thank you very much

Hi,

Function you are looking for is match().

Match returns an error if there are no matches so no need a test before its use.

Here are my 2 cents worth.

I would only calculate the values:

And, although not absolutely necessary, I would define auxiliary functions

and use them to make the desired stability outputs based on the data:

Example using different data:
