Hi there! Up here is my simple code. It has to simply send sms. But i don't know how to click button "Wyślij SMS" (eng. "Send SMS"). It has no name. That's what i found:

<input type="submit" class="btn" value="Wyślij SMS !" alt="Wyślij" src="/sms.szyderca.com/images/wyslij_sms.jpg" onclick="return nom();">

Plz help me how to click it oO

edit: FormSubmit doesn't work too.

You can find the object by numerating, look at the function _IEFormElementGetCollection (or similar).

Also this part is Javascript: onclick="return nom();"

You can run the function nom by doing this: _IENavigate($oIE, "javascript:nom();")
