I'm trying to include a ticket order form on a WordPress page. It includes two select lists. I had it all looking and working fine, but at some point WordPress started adding opening and closing tags to the option tags, so
<select name="os0">
<option value="Will call">Will call</option>
<option value="Mail tickets">Mail tickets</option>
</select>
becomes
<select name="os0">
<option value="Will call">Will call</option></select>
<select name="os0"><option value="Mail tickets">Mail tickets</option></select>
</select>
This seemed to happen when I made changes to the CSS file in the child theme. I'm quite new to WordPress but not to html, php, mysql, etc... What in the world am I missing here? I'm adding all the code to the page using the HTML tab, then clicking Update and everything looks good. Until it changes! This has happened three times in the last hour and it's got me confused. Any assistance would be greatly appreciated!
