when explaining the conditional Type 1 (If + simple present, main clause: will-future, simple present or modal + base form) the following question arose:
Which time will be needed in the main clause in the following sentence:
If the online button is illuminated, you ??????? (to make) a mistake.
Do you just need present perfect (have made) or future 2 (you will have made) or what else do you need here?
IŽd be very happy to receive an explanation.
Thanks in advance.
