How to use control value

I am trying to use the control value to know whether the correct page loaded or not. For that i used the following steps.

Find Control - In that i used select control to scrap a unique field in that page. and saved it to a control value variable

If command - Checking the above saved control value

True - If the above value is true then going to next step

False - if the control value is false - then go back to previous step.

But when i test the result, it always showing false eventhough the page is correct. I selected different fields. still it is false. Is there any mistake in my steps ? Whether the control value is not the one for this ?

There is already pageload wait, Whether sleep is needed ? This is just a twitter login check, whether login is successful or not.

still the if test giving me false. can you please give a example on checking the site page with if command.

Please tell me the correct usage of Control Variable

If there is control found you have to place further code on false statement not on true. If (control1==Null)

True=....

False=place your code.
