I'm having trouble with the Patch function when using a radio button

[Rg4963]

When using the patch function for the radio button it's not working for me maybe I have the wrong formula.

Hi @Rg4963 

Assuming you are patching to a text column type (Attending), Use

DataCardValue4.Selected.Value

DataCardValue4,Selected. (intellisense will guide you through)

Hey,  so I added that now everything underline with red.

It's even giving me that when just having the data card.

If you hover over the red underlines, it will tell you the exact reason for the error

Hi @Rg4963 ,

Could you tell me the data type of Attending field?

What I need is the error message when you use "DataCardValue4.Selected.Value", could you show me it?

Could you show me the formula of DataCardValue4's Items?

If Attending field is special data type, you need to use special formula.

For example, if it is a choice type then you need to use this formula to update:

Attending:{Value:DataCardValue4.Selected.Value}

Best regards,
