Validation in a repeated grid

[Mani]

Hi Alex, need some help with validation in repeat grid.

I have a case where if in any row/iteration "dropdown = third choice and amount >= 2000" then the comments control in that row/iteration must be made mandatory. 

Thanks

Hi Manish,

The following expression will do the trick: `$dropdown = '3' and
xs:decimal($amount) > 2000`. You can see the result in the screenshot below,
and I've also attached the updated form with this change. You'll let me know
if this works for you.

Thanks Alex. Works perfect!

But the drop-down values cannot be selected more than once. Every row must have a unique dropdown value. How do I do that?

Hi Manish,

You can use an expression along these lines, and I've also linked to an
updated version of the form below. You'll let me know if this works for you.

let $current := .
return count(//dropdown[. = $current]) = 1

Hi Manish, did you get a chance to try the expression checking that the
selected value is different on every row? If so, did that work for you?
