What is the HTML type of the element `skip_ad_button`? Is it an `input`, a `button`, or something else? Regardless of the answer, it is clear that you cannot set the `InnerText` property of that element - perhaps you need to set an attribute in order to accomplish whatever it is you are trying to accomplish... — RB., Jun 13 '17 at 12:32

I have try to set option strict to on but it continue to give me the same error how can i solve it — Andreia Gosalves, Jun 13 '17 at 13:01
See @RB comment. what if you try `skip_ad_button.setAttribute("value", "skip_ad_button")` versus `skip_ad_button.InnerText = ...` — Jimmy Smith, Jun 13 '17 at 13:32
Tank you @JimmySmith Now I Have No More Errors but wen the page is load and my website its come the button its the but there is no automatic click at all — Andreia Gosalves, Jun 13 '17 at 13:47
Glad! When you say no automatic click, you cannot click the button now or it won't programmatically click it for you? — Jimmy Smith, Jun 13 '17 at 17:16
Sorry what i mean its it should catch the attribute but nothing happen — Andreia Gosalves, Jun 14 '17 at 13:05
