[Plugin: Contact Form 7] tabindex not working

Hi there, tabindex isn’t working for me in my form. It appears to be formatted correctly, according to the CF7 site, which defines, [TYPE NAME CLASS ID OPTIONS]

<div class="container_16 ucf_app_form_padding">
	<div class="grid_3 alpha">
		<p class="small">Company/Business Name</p>
	</div>
	<div class="grid_4 suffix_1">
		[text* CompanyName id:companyname class:ucf_apply_online_text_field tabindex:1]
	</div>
	<div class="grid_3">
		<p class="small">Company Registration Number</p>
	</div>
	<div class="grid_4 suffix_1 omega">
		[text* CompanyRegNo id:companyregnumber class:ucf_apply_online_text_field tabindex:2]
	</div>
</div>

Above is an example code block – all my fields follow similar lines.

Any hints?

Thanks,

Alan
