On submit it saves the first select to the database, the second and third never submit, and this error appears saying the join formatter expects an array

This is a test page to please try

What are the names of the selects? When using multi selects make sure to add [] to the end of the names.

Name them like record[0][select_vals][].

This is what i have currently

<body is="dmx-app" id="testingteo">
	<div class="container">
		<div class="row mt-5">
			<div class="col">
				<form is="dmx-serverconnect-form" id="serverconnectform1" method="post" action="dmxConnect/api/testing/testing-ms-multi.aspx" dmx-generator="bootstrap4" dmx-form-type="horizontal">
					<div id="record" is="dmx-repeat" dmx-bind:repeat="3">
						<div class="form-group row">
							<label for="inp_select_vals" dmx-bind:for="insp_select_vals_{{$index}}" class="col-sm-2 col-form-label">Select vals</label>
							<div class="col-sm-10">
								<select id="inp_select_vals" class="form-control" name="select_vals[]" dmx-bind:id="insp_select_vals_{{$index}}" dmx-bind:aria-describedby="insp_select_vals_{{$index}}_help"
									dmx-bind:name="record[{{$index}}][select_vals]" multiple="true">
									<option value="1">Option One</option>
									<option value="2">Option Two</option>
									<option value="3">Option Three</option>
								</select>
							</div>
						</div>
					</div>
					<div class="form-group row">
						<div class="col-sm-2">&nbsp;</div>
						<div class="col-sm-10">
							<button type="submit" class="btn btn-primary">Save</button>
						</div>
					</div>
				</form>
			</div>
		</div>
	</div>

I added the [] to the name parameter, but havent done anything with the dmx-bind:name?

Thanks Patrick, I ave always added the [] to the name field, but never done it on the bind name too, I just added it and it works now, so my final code looks like
