technically both functions do, but as strongly as i harp about using only property() to get properties, i say the same about only using index() to get indexes.

Thank you very much David

I think this can be very, very easy.

index() and property() both do the same thing, but index() also does numerical indexes.

property(local!cdt, "value", {}) returns the "value" column of a single local!cdt. It returns an array of "value"s if local!cdt is an array. Same for index().

local!cdt: {{id: 1, value: "A"}, {id:2, value: "B"}, {id:3, value: "C"}},
index(local!cdt, "value", {})

Should return {"A", "B", "C"} No looping required; property() and index() should both automatically loop for you.

Once you have 5 text strings, just a!forEach( items: local!textStrings, expression: richText(....text: fv!item, ....))

If you need to combine elements, gather your CDT in a local like you're doing now, then a!forEach( items: local!CDTData, expression: richText( . . . text: property(fv!item, "name", {}) & property(fv!item, "someOtherField"), ....))

expression: fv!item.emptype)[1],[/quote]

I'm not really sure what you're trying to do here, but this specific piece of code will manually index the first ([1]) result of the array generated by the a!forEach() loop, basically making it meaningless. I think it might be closer to your desired end result just by removing the "[1]".

Also: for code like this (or any SAIL or expression code really) I strongly suggest inserting your code into a Code Box ("Insert" --> "Insert Code" in the in-editor menu here), as this retains formatting like indentation and uses an easier font for reading code. When asking others to review your code it's a good idea to make it as easy to read as you can.

I am using the below codes..It is ok?

a!localVariables(
local!empData:rule!FF_EMP_QE_EmpType(typeId: null),
{a!columnsLayout(
columns: {
a!columnLayout(
contents: {
a!cardLayout(
contents: a!richTextDisplayField(
value: {
a!richTextIcon(
icon: "money",
color: "ACCENT",
size: "LARGE"
),
char(10),
a!richTextItem(
text: a!forEach(items: local!empData,
expression: fv!item.emptype)[1],
/*text: local!empData[1].emptype*/

size: "LARGE")

},
align: "CENTER"
),
/* Setting this variable would be used to navigate to a category of answers */
/*link: a!dynamicLink(saveInto: a!save(local!category, "Finance")),*/
height: "AUTO",
marginBelow: "STANDARD"
)})})})
