To simplify a project where multiple steel frames are being designed I've incorporated the use of "include worksheet" in MathCAD prime 3.1
All the worksheets include a worksheet that has basic quantities calculated, like a parent - multiple child relationship. I've now tried to have one of the child worksheets include another child worksheet and I get the errors in the attached image. Reloading the worksheet has eliminated the green error but the red error persists. The included worksheet has no errors. Are there any limitations to including worksheets that would not allow this include to work?
