Request for Assistance with Power App ComboBoxes - JSON

Posted on by perez1

I have a question about MS Power App. I have a data source from a SharePoint list with three columns (PRJ, BT, EB). In the Power App, I have a window with three ComboBoxes. The first ComboBox reads all PRJ data.

The second ComboBox reads the resulting values from the second column BT. I use following code in "Items" -> ForAll(Table(ParseJSON(varJSONTest)),{cc:ThisRecord.Value.BT}) and it works fine.

From there, I select only one result. The third column EB should then offer me the options to choose from. Again, I select only one option.

The content of the third EB column in the SharePoint list looks as follows -> {"BT":"0","EB":"0"},{"BT":"21","EB":"1OG"},...

What should the code for the last ComboBox look like? Does anyone have experience with this?

Hi,
I have tried the following code
ForAll( Filter( Table(ParseJSON(varJSONTest)), cc.BT = selectedBT && cc.PRJ = selectedPRJ), {cc: ThisRecord.Value.EB} )
but unfortunately without success.
Note that the selection of the first ComboBox is in a variable called selectedPRJ and the selection of the second ComboBox is in a variable called selectedBT.
Maybe someone will see the mistake?

Br,
