Help with script

[JChau405]

im trying to make an if else statement, where if this text/element text is shown on chrome browser it will either continue with the script or close the browser and restart.
also another scenario if this text/element text is shown on chrome browser delete text input and move on to the next part of the script

thanks in advance

to clarify, my script has a list of codes that is input into the box
