Firing Events on a webpage with vbscript

Hi guys, i made a vbscript to log on ticket tool online and create a ticket automatically. The problem is that some fields are filled only when a event is fired. so i need to fire that event from my script, is that posibble ?

here is part of the HTML CODE:

<td control="true" id="mx1851[R:3]" onmouseover="appendClass(this.parentNode,'trh')" onmouseout="removeClass(this.parentNode,'trh')" onclick="sendEvent('click','mx1851[R:3]','','');event.cancelBubble=true;" style=";" currentrow="false" class="tc hl cursor_hand">...</td>


how can i fire that "sendEvent('click','mx1851[R:3]','','') ????

i tried generating a click, objIE.Document.getElementByID("mx1851[R:3]").click , but doesn't fire any event, and nothing happened..
