One of the terms in the STP equation requires it's variable values to be within a specific range. The term is "((2000 - sbLCL) / 1000)" using the variable sbLCL. When sbLCL is below 1000, it should be set to 1000. When sbLCL is above 2000, it should be set to 2000 (e.x. 130 should become 1000, 1350 should remain 1350, and 4000 should become 2000).</div><div><br></div><div>I know this calculation will definitely involve manipulation with the <i>maskout()</i> and/or <i>const()</i> functions but I have no idea where to begin.
