Variable Time for the same stimulus

Hello everyone

I have read all topics and nothing to help me.

I have create a routine and a loop to make a word appeard on the screen, with an Excel file, and it works.

However, I need to make that if the answer is correct, the second word appeard. But if the answer is wrong, I need to make appeard the same word with a longer Time than the first.
(2 sc vs 1 sc the first Time the word appeard)

Can you help me please? I appreciate very well and sorry for my bad english !

Thank you!
Erika
