I am getting the following error while trying to click on a link:

This page that I am testing uses a table design where the "links" are simply the table cells that have been assigned the 'onlick' method that runs a javascript. Example:
<table border="0" cellpadding="0" cellspacing="0" align="center" style="width:85px; height:;" onclick="javascript:Click1('Admin.aspx?')">

In order to record this I have tried both clicking on the link and assigning "left click" from the blue bubble menu. While record it works but when playing back the recording I get the above error.

Hello Ben,
    we will need as much info as possible in order to troubleshoot this. First off could you please record a Jing video demonstrating how the issue occurs.

Hope to hear from you soon!

I have seen a few other posts where other Telerik staff have setup GoToMeetings. Is this an option? I have a couple other things I am having issues with that I  would like to demonstrate as well.

Hello Ben,
    GoToMeetings are generally a last resort. Also, they are not always practical. It could be that you're encountering some complex issue that requires deep troubleshooting. A GoToMeeting doesn't allow for that - it's quite possible we won't be able to solve the issue on the spot.

With all of this in mind I would like to learn as much as possible about the problem before we proceed to a GoToMeeting (if necessary). Please go ahead and post separate tickets/forum threads on your other problems.

Hope to hear from you soon!

Best wishes,
Stoich

some more details.......
The site that I am testing uses frames pretty heavily.  What I have found is that for the step that is producing this error, the playback in the tool is looking for this particular element in the previous (non-visible) frame. 
Is there a way that I can put a verification step just before this in the playback that will confirm which frame is visible?

I was unable to attach a Jing video....it only allows me to save a video as swf and I am unable to attach that type of file here.

So, I have attached the following screen shots....
1. failureSummary.png - this image shows the error that is showing up when trying to click on the link
2. frameError.png - this image shows the test execution screen for my test in WebUI. 

What I have noticed is that I get this error on playback when it tries to click on the link in the table cell 'Td1TableCell'. 
In the 'Elements'  portion of the window, I notice that this table cell is being assigned to the incorrect frame(FrameFRMain). Is there a way that I can manually assign this element to the correct frame.

 - Step 8 - 'Click S1TableCell' is located on the first frame. 
 - Once I login, steps 9-12, it switches to another frame
 - I then click on the 'Td1TableCell' link on that frame.  However on playback it thinks that this link(table cell) is on the previous frame.


I hope this additional information helps....

another question, was not sure where to put this.....

 I have the pricing breakdown as given at the end of the webinar for all of the different products. However, are there any yearly fees that we would pay.  What about training/support/software updates.  How are these handled and what is the pricing structure?

Hi Ben,

The website will accept .zip files. You can put the .swf inside of a .zip file and attach it that way. Personally I like using Screencast (which is also free). I upload my video to Screencast (which Jing nicely integrates with) then post the link to the video.

The initial purchase price includes a 1 year subscription to priority support and access to all new versions we release. After that you are free to use the software as long as you like. There is a subscription renewal fee. The pricing is listed here.

I'll make sure that Stoich gets this ticket just the same.

Kind regards,
Cody

Hi Aruna,
unfortunately it seems to me that you might have posted this in the wrong place. The stack trace you've provided doesn't seem to be related to Test Studio in any way (in fact it doesn't seem to come from a test). 

Is you're issue related to Sitefinity perhaps?
