Dataverse Choice Column Comparison

Hi,

I have a form where I want to make a field required if a dropdown contains a particular value. The values for this dropdown are taken from a choice column in the Dataverse called Calculation.

I thought I could just do:
If(DataCardValue4.Selected.Value = 100000002, true, false)

or:

If(DataCardValue4.Selected.Value = "Average by Week", true, false)

100000002 is the numeric value of the choice in the Dataverse. I get an error that says "Incompatible types for comparison: These types can't be compared: OptionSetValue(Calculation), Text

Does anyone know how to do this comparison? Bear in mind, I am not checking a value in the Dataverse table, just checking what value is currently selected in the dropdown on the data card for the form.

Thanks

Sean

Hello @SeanHenderson,

You can try below code

If(DataCardValue4.Selected.Value = 100000002,'COLUMNNAME (TABLENAME)'.TABLEVALUE,true, false) (Eg) 'Status (Booking Updates)'.Active

Hi @rampprakash

I'm not sure what you mean by COLUMNNAME (TABLENAME)'.TABLEVALUE.

For testing, in the Dataverse I have a table called CTRs and a choice column called optionTest.

This is on a new form, there is no value stored in the Dataverse to look up for the record. The condition needs to be entirely dependent on what is currently displayed in the Combo Box for the datacard.

Hello @SeanHenderson,

As per your previous chat,

Table Name : CTRs
Choice Column Name :optionTest
Choice Column Name : Average by Week

So you need to Try below

If(DataCardValue4.Selected.Value = 'otionTest(CTRs)'.Average By Week,true, false)

Thank you, that did it. I needed to reference the name of the choice not the name of the choice column.
