Much like Titus has discovered, I'm a idiot. <br><br>Added a 'showforms' prior to filling it out.<br><br>Added 'single quotes' around the checkbox value instead of double quotes. <br><br>fv("1", "sys_req", '1')
<br>fv("1", "terms", '1')<br><br>Added another 'showforms' after filling it out - just to make sure. <br><br>And it works. <br><br>Sorry for the noise. <br>
