Invoking Click (or something) on HTML List

Hi all, I've come across an HTML listbox that I requires a selection but I do not know how to set its attribute via VB. I thought that

Code:

.GetElementById("exporterId").SetAttribute("value", 7)

where 7 would be the index representation of the selection I want to automate. This does not work so I also tried to invoke a click but I don't know how to apply that to an HTML list. I'm stumped and I hope I have been clear.

The value of a listbox is the value that is selected. Not the index. So set it to the value you want to select.

Thanks AtmaWeapon, I'll try that as soon as I can and let you know how it goes.

Hi AtmaWeapon, I tried

Code:

WebBrowser1.Document.GetElementById("exporterId").SetAttribute("value", "CSV file, time as rows")

and I also tried

Code:

WebBrowser1.Document.GetElementById("exporterId").InvokeMember("click", "CSV file, time as rows")

but neither select from the list. "exporterID" is the name of the list for certain. I'm slightly off on this and don't know what to add to the code to make the selection work. Any thoughts?
EDIT: I have also tried the GetElementByTagName with <option value> as its parameter

Code:

WebBrowser1.Document.GetElementsByTagName(ListTagName)

where ListTagName is a string but I don't understand what to do with it if it is found.
HTML and the selection I am after is in red:

Code:

<select name="exporterId" size="12" id="OutLst">
            <optgroup label="SCREEN OUTPUT formats">
                <option value="SERIES_HTML_TIME_AS_COLUMN">HTML table, time as columns</option>
                <option value="SERIES_HTML_TIME_AS_ROW">HTML table, time as rows</option>
                </optgroup>

                <optgroup label="DOWNLOADABLE FILE formats">
                    <option value="SERIES_CSV_TIME_AS_COLUMN">CSV (comma-separated values) file, time as columns</option>
                        <option value="SERIES_SCSV_TIME_AS_COLUMN">SCSV (semicolon-separated values) file, time as columns</option>
                        <option value="SERIES_CSV_TIME_AS_ROW">CSV file, time as rows</option>
                        <option value="SERIES_SCSV_TIME_AS_ROW">SCSV, time as rows</option>
                        <option value="SERIES_CSV_TIME_AS_COLUMN_DATA_QUALITY">CSV file, time as columns with data quality indicators</option>
                        <option value="SERIES_SCSV_TIME_AS_COLUMN_DATA_QUALITY">SCSV file, time as columns with data quality indicators</option>
                        <option value="SERIES_CSV_TIME_AS_ROW_DATA_QUALITY">CSV file, time as rows with data quality indicators</option>
                        <option value="SERIES_SCSV_TIME_AS_ROW_DATA_QUALITY">SCSV file, time as rows with data quality indicators</option>
                        </optgroup>
            </select>

I set my value wrong, the following works. Such a silly mistake. It's all good now though.

Code:

WebBrowser1.Document.GetElementById("exporterId").SetAttribute("value", "SERIES_CSV_TIME_AS_ROW")
