LPL question - Make a field required based on selected value of another field

Looking to make a field required ( in Yellow) based from the selected value ( in Green). If selected value in green is "REPLACEMENT" then the field Replacing becomes required.

I've tried setting up Field rules but with no success - any ideas on how to solve this?

LPL Code that I've tried:

Field Rules

Replacing
if (JobRequisition.ReasonForOpening.value == "REPLACEMENT")
required

You look like you are on the right track. I'd suggest trying the following small tweaks:

Remove the ".value"
Use a single equal sign to test for equality rather than two

Like so:

Field Rules
    Replacing
        if (JobRequisition.ReasonForOpening = "REPLACEMENT")
            required

I am on an older version of SyteLine (9.01) but can't you open the form in Design Mode, right click on the Replacing ComboBox. Under the component properties expand the Behaviors. Click the ellipse(...) for Required When property. It then should let you create a "clause" that states when the component for "Reason For Opening" = "REPLACEMENT" .

The Edit Left and Right buttons let you select a Literal, Variable, Component, or Property. Left value would be your component or property for the "Reason for openning" dropdown while the right you would specify as a literal of "REPLACEMENT"

Have you tried using a constraint on the form itself nested beneath the yellow field? The LPL would looking something like:

Replacing

constraint(GreenFieldName = "REPLACEMENT" and YellowFieldName entered)

"ReplacingFieldRequired"

Constraints are tricky and not sure if the "entered" operator would work here...but if it does you might would need to include the other options in the green field using the or operator...something like:

Replacing

constraint(GreenFieldName = "REPLACEMENT" and YellowFieldName entered or (GreenFieldName = "Option2" or (GreenFieldName = "Option3" or (GreenFieldName = "Option4"))))

"ReplacingFieldRequired"
