Trouble with replacing string in dynamic input

[crtakacs]

I'm trying to use the dynamic input tool with a prompt to have the user enter a date as the input. I wanted the default text in the prompt to show up as "MM/DD/YYYY" but I'm having trouble. Below is my layout - would someone be able to assist?

why wouldn't you use a date selector instead of a text input box?

you can also attach an error tool with something like

regex_match([field],"\d{2}/\d{2}\/d{4}") as the expression to evaluation...

Also - I believe your dynamic input SQL criteria should reflect the name of your field (ie [Enter Business Date]) since that will contain the updated MM/DD/YYYY
