I am trying to calculate the output value for set of equations saved in the database by giving the input via xojo in the front end. I am able to connect the database successfully. I am able to get the output for few equations. Few lengthy equations are giving -nan(ind) as outputs. I need to find out why this happens and need solution how to solve it.

I am new to Xojo.

Kindly help me in this regard.

Thanks in advance.
