Unquie code on submitting a form?

Is there a way that when a customers has filled out the form and a the 'Thank You' message appears that they also get a unique code/receipt number? 

Have now found how to do this but it will not show the code on the Thank you page even after I have copied the id tag in, anyone know a solution?

Thanks

Colin

Hi,

To include the unique ID in your thank you page, open up the thank you message customization window in the form builder then select "Thank you message":

Then click on the the field ID for your unique ID field in the column on the right to add it to your thank you message:

And you should be good to go:
