In FM6, can calcutation to to a specific layout.

Case (Pricing = "Custom", Go to Layout (Custom Quote))

or Case Pricing = "Custom), perform script(XXXXXX)

Hopefully someone is working this evening or Saturday and can help.

thanks in advance

This can be done with script steps, not a calculation.

If [ whatever condition ]
Go to Layout [ some layout ]
Else
Perform Script [ your script ]
End If
