If / Else If

Hi, I have a Use Case where in i have 2 text box, First Name and Last Name. I want a label to display Error Message

If txtFirstName equals ‘’"" then errFirstName Show
If txtLastName equals “” then errLastName show.

But i couldnt get the 2nd if, It is always saying Else If. How can i make the Case 2 as If instead of Else If

Yours Sincerely

Sorry, I got the answer, Use Toggle If/ElseIf by right clicking Case.

Dont be sorry man. Actually, I just sign up to show my gratitude to you. It’s surely a small problem but indeed troubled me for not a short while. Thanks for your answer!
