How to click next and back on TextLabels inside Surfacegui on my training kiosk?

I have a kiosk that I want players to be able to click on to get information. I want the player to be able to click and read, click and read...through the several different slides. I have a Surfacegui, inside are 3 Frames...One is IntroFrame with two TextButtons inside it for JobA and JobB. One is JobAFrame with 12 TextLabels inside it. One is JobBFrame with 14 TextLabels in it. At the beginning, in it's own Frame, are two different buttons, one for JobA and one for JobB. When a player clicks JobA, I want the player to click through the 12 slides for that JobA. When they are done, I would like it to loop back to the IntroFrame that has the two TextButtons in it. When a player clicks JobB, I want the player to click through the 14 slides for that JobB; and then loop back to IntroFrame. I would like to enable the player to click back and forth at will. Can someone please help me script this?
