You should ALWAYS attach the Mathcad/Prime worksheet, not just a picture.

Apart from that:

- In the definition for Icr, you should explicitly type a multiplication symbol   *  

        between As' and (dc-d)

       as well as between As and (d-dc).

If not As' and As are considered functions.

- If you only need numerical results, you should use the root function, or a solve block, to determine the value of dc.

Note that the symbolic processor of Mathcad/Prime does not 'know about units' by default.

But first: attach your worksheet.

Success!

Last equation. After you can solve dc, then put the answer to dc. 

Unit of right first is m^2, second and third are m^4. So can't solve.
