Enkele gebruikelijke fouten, kijk naar de tooltips
Variabelen gebruiken voor definitie: notSetYet
Onbekende functie: iff(numPets > numKids,1,2)
Onbekende variabele: sum(age,num_pets,numKids)
Verkeerd aantal parameters: sprintf(),if(1,2),date()
Read-only variabelen wijzigen:TOKEN:ATTRIBUTE_1+=10,name='Sally'
Unbalanced parentheses: pow(3,4,(pow(3,4),pow(3,4))
