<div class=""><br class="">

<div class="">I tried for width by adding in a validation line:</div>
<div class=""><br class="">

<div class="">
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>VALIDATION</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>'pin' '^[0-9]{12}$'</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>'qstring' '^[0-9]{12}$'</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>'width' '^[0-9]{5}$'</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>END</div>
