Put choices picked into a textbox

[kayaking]

Hi everyone, I have 2 radio button fields on my list form. One contains the options:

• Option 1
• Option 2
• Option 3

The other contains the options

• Option 4
• Option 5
• Option 6

If a user picks Option 1 and Option 5, I want to automatically populate a texbox field with the following, "1,5". Is this possible?

Use the Concat expression and you will be able to combine the radio box 1 and radio box 2

@sbonera How would I simplify the choice though? For example, "option 1" needs to become just "1".

Also, when trying to concat the two radio buttons, my values are appearing like this:

	
[{"@odata.type":"#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference","Id":0,"Value":"Option 1"}][{"@odata.type":"#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference","Id":0,"Value":"Option 5"}]

Any ideas why?
