Calculation form on your website
Only the distance calculation form is installed on your website - your visitors fill it out and after clicking on the button "Calculate" they are redirected to the website Flagma.cn to see the calculation result.
You may change the form code at your discretion.
If your website uses character encoding different from utf-8, e.g. windows-1251, please add the following into the code form:
<input type="hidden" name="charset" value="windows-1251">
