Button: Calculate Function: Calculation Results Error Type: System is -nan(ind) psi

Description:

After calculating the system, the results show, "Your System Has a Deficit"

System is -nan(ind) psi over the Water Supply Curve

Cause:

The end user somehow got a negative sign into the Fittings column

Solution:

Don't put negative fittings in the Ftgs column

Cause:

Missing water supply information

It's possible the -nan(ind) is legit if a demand calc is being run.

Solution:

Verify you have a legitimate water supply in the calculation
