Pass global variable value to select drop down option (single select)

[Sumit_Mathew]

Hi,

I am new to Power Apps. I am building a power app customising a SharePoint form. One of the columns is a drop-down, called 'Category'.

I am setting the power app in such a way that all these drop down options are in the form of buttons in the layout. Based on which button the user clicks, I want the column 'Category' to get updated with the button value selected.

For eg. Buttons are A, B, C, D, E, F, G..these buttons also represent the drop down options in Category field.

If I select B, I want the drop down in the Category field to get updated as 'B' and then send this value back to SharePoint on submission of the form. 
I have set a global variable as 'varCategorySelection' which has the value of the respective button selected - so in this case 'B'.

I am trying to set the 'Default' property of the dropdown equal to varCategorySelection, but it is not working. 

What can I do to resolve this ?

On Select property of each button:  Set(varCategorySelection, "A")    

Replace "A" based on the button choice such as "B" or "C" and so on.

For drop down's default value:

LookUp(Choices([@<SharePoint List Name>].<Choice Field Name>),Value=varCategorySelection).Value

Please same formula in the Update property as well.
