Hi All,

Trying to set a variable when a drop-down value is equal to no I have the below on the drop downs "OnSelect" the drop down itself is also a variable "var_dropdown"

If(dropdown.SelectedText = "No"),Set(var_output , "TEXT")

Any suggestions would be greatly appreciated

Re: Set Variable from drop down

Hello @Mclean2023 ,
Here is the tested code for the onChange property of Dropdown box.
Please let me know if it works.

If(Dropdown1.Selected.Value = "Yes", Set(var_output, "Text_1"),
Dropdown1.Selected.Value = "No", Set(var_output, "Text_2"),
Dropdown1.Selected.Value = "N/A", Set(var_output,Blank()))

Re: Set Variable from drop down

need to make small update on this, need another option. When i update the formula, I don't get an error, but nothing happens when running it. the first part still works by adding no but if I change the drop down to yes, the no stays in the field.

If(dropdown.SelectedText.Value = "No",Set(var_output , "TEXT_1") ||
If(dropdown.SelectedText.Value = "Yes",Set(var_output , "TEXT_2") ||
If(dropdown.SelectedText.Value="N/A",Set(var_output ,Blank())))

Hi , @Mclean2023

Yes , you need to put this code to "OnChange" property which means Actions to perform when the user changes the value of a control (for example, by adjusting a slider).

Hi , @Mclean2023

You can try to use this code:
If(dropdown.SelectedText.Value = "No",Set(var_output , "TEXT") )

The ".Value" is the column Name in your dropdown control - items columnName;For example , if my items column Name is "Col1", i need to use this expression:
If(dropdown.SelectedText.Col1= "No",Set(var_output , "TEXT") )
