Could you share the code so I can take a look at it? This looks awfully lot like an internal MakeCode issue

[technonux]

Seems like it just randomly fixed itself

[YuHayate]

why are you using a while loop? use a for loop (you can still get “i” from the for loop)

for (let i = "StartValue"; i <= "end value"; i++) {
        
}

also if you whant to add one to a variable just do var++ it adds one to var

Haven’t seen the code, but since it’s a code Parser it’s possible he needs to shift the index around, which you can’t do in a for loop if i’m not mistaken. Could be wrong, though
