Hi all,

I'm having issues and wondered if there's anything obvious? the varSelectDate is from the on change of my date picker,

If(ctxLoadPeople,
//Load People
ClearCollect(colPeople,
AddColumns(Sort(EngineerNames,FullName) As Contact,
Zone,
"People",
PersonaImage,
    If(!IsBlank(Contact.EntitiyImage),Substitute(JSON(Contact.EntitiyImage.Value,JSONFormat.IncludeBinaryData),"""","")),
    Initials, 
    Mid(Contact.'First Name',1,1) & Mid(Contact.'Last Name',1,1)
    )
);
UpdateContext({ctxLoadPeople:false});
If(ctxLoadDaySlots,
// Create Day Slots
ClearCollect(
    colDaySlots,
    ForAll(
        colPeople As Person,
        {
            Person: Person,
            Days: ForAll(
                Sequence(DaysinRange) As Day,
                {
                    PersonId: Person.FullName,
                    Day: Day.Value,
                    Zone: $"{Day.Value}|{Person.FullName}"
                }
            )
        }
    )
);
UpdateContext({ctxLoadDaySlots:false});
If(ctxTaskEvent,
ClearCollect(
    ColTasks,
    AddColumns(
        ProjectTasks,
        TaskName,JobDetails,
        Zone,
        If(IsBlank('Assigned To'),
        "Unassigned",
        $"{DateDiff(VarSelectedDate,'Due Date',TimeUnit.Days)+1}|{'Assigned To'.Contact}"
        
        ),
         Edited,false
    )
);
UpdateContext({ctxTaskEvent:false});
);

Assuming that the two values in the DateDiff are correctly formatted dates.

Datediff returns a number. Thought it would convert it to text. Try adding a Text function around it to convert it to text

Hi,

from watching the video i'm following, https://www.youtube.com/watch?v=wkHvjusgLEE&t=326s the part is 5:14

what i'm trying to achieve is to create a unique ID with the first part being a date from my dataverse column Due Date and then a | with the second part being a persons name so i should have something like

28/01/2025|John Smith

the thing i can't figure out from the video is where he's got that variable from. I only have a date picker and a label which have anything to do with date. I'll add the code for them further down.

$"{DateDiff(VarSelectedDate,'Due Date',TimeUnit.Days)+1}|{'Assigned To'.Contact}"

from label

Text(DateAdd(DatePickerCanvas1.SelectedDate,ThisItem.Value-1,TimeUnit.Days),DateTimeFormat.ShortDate)

from date picker

Select(fnLoadTasks_2)

@jsmith87 Hi,

I think in your code, you assigned JobDetails to TaskName. do you mean TaskName, "TaskName",JobDetails,"JobDetails" ?

$"{DateDiff(VarSelectedDate,'Due Date',TimeUnit.Days)+1}|{'Assigned To'.Contact}"

{DateDiff(VarSelectedDate,'Due Date',TimeUnit.Days)+1}, looks correct,you have to make sure VarSelectedDate and 'Due Date' is the same date type, this one return a integer.

'Assigned To'.Contact, this part you have to make sure it is a text.

try those checks first.

good luck.

Hi Stampcoin,

Thanks for the tips, still no joy (it's certainly me!)

following your advice I went back to my dataverse table and added a date column. Which I have named Due date. So with varSelectedDate coming from my data picker and having a dataverse table column with date fomat they should be both the same however i am getting the below error.

Also regarding JobDetails to TaskName. do you mean TaskName,"TaskName",JobDetails,"JobDetails" ?

I honestly don't know, I thought following a video step by step to enhance my knowledge would be a good way to learn. I was wrong.... in my dataverse fields i have:

I think what the video is trying to achieve is that if in the dataverse table someone's name is in the assigned to and there's a date it will combine them both with | between the name and date. Does this help at all?

jsmith87 Hi,

some tips:

make sure VarSelectedDate,'Due Date' both are date type, you can add a label, and assign the label text= VarSelectedDate, another label, assign text='Due date'. the purpose is to identify both have the correct data

identify 'Assigned To'.Contact} make sure it is text type value.

another easy way is like this:
$"{DateDiff("2025-04-16","2025-04-19",TimeUnit.Days)+1}|{"John Doe"}"

then you will know which part has problem.

feel free if you need more help.

stampcoin thank you that's working now, the only issue is that Contacts are a table i believe and the dates need to be changed to text. I don't suppose you'd be ok with a call to help me resolve this issue? if that's ok i'd really appreciate it, i'm sure it's something you'd be able to resolve in seconds

If(ctxLoadPeople,

//Load People

ClearCollect(colPeople,

AddColumns(Sort(EngineerNames,FullName) As Contact,

If(!IsBlank(Contact.EntitiyImage),Substitute(JSON(Contact.EntitiyImage.Value,JSONFormat.IncludeBinaryData),"""","")),

@jsmith87 Hi,

I am heading for lunch... here is an reference for you.

NewColumn, $"{DateDiff("2025-04-16","2025-04-19",TimeUnit.Days)+1}|{'Status (Contacts)'.Active}"

'Assigned To'.Contact, is this correct format ( didn't watch the video...).

the format should be columnname(tableName).value ( see my example), or some property you can refer to.
