Hello -

I have a form and items are in groups. When the form is submitted, the code checks to make sure you selected at least one item in a group. If you missed a group, it adds the group number to a variable with a comma. So if there are 5 groups, the error variable may look like this:

1,3,5

Then on the next page, I do a

var('errors') = $error_marker->(split:',');

Which I think makes it an array. Bear with me here.

errors = array((1),(3),(5))

Then further down the page I iterate through the array and show error messages to the end user:

[if(var('errors')->Size > 1)]

<div class="alert alert-error">
<strong>FINALIZING CANNOT COMPLETE</strong><br>
[iterate: $errors, (var('theErr'))]

['You must select at least one rating from Group ' + $theErr + '.<br>']
[/iterate]
</div>

This seems to work fine until there is ONE error. The conditional would be false and not show the error. So I added an equals sign:


[if(var('errors')->Size >= 1)]

<div class="alert alert-error">
<strong>FINALIZING CANNOT COMPLETE</strong><br>
[iterate: $errors, (var('theErr'))]

['You must select at least one rating from Group ' + $theErr + '.<br>']
[/iterate]
</div>

However, now when there are NO errors, it still shows the DIV presumably because the value of $errors is still 1.

I'm confused and not sure what to do.
