how do I fix this error message?

[vapid harness]

This is for an obby checkpoint system I'm trying to make but it's not working

[sudden flame]

your trying to do a subtraction on an instance

num - instance

What even is the a CurrentStage?

Is ita number value?

[white folio]

CurrentStage.Value

[olive jasper]

CurrentStage is a folder which is an instance not a value.

you’re doing a number - an instance which breaks the code

[vapid harness]

I see

how do I make it a number?

[vapid harness]

didn't work

[olive jasper]

show me your current stage and its children in the explorer

[vapid harness]

this?

[olive jasper]

try some debugging like
if spawnStage and (spawnStage - CurrentStage.Value == 0) then
remaining code

[vapid harness]

fixed

but thanks

if (spawnStage == CurrentStage.Value + 1) then
CurrentStage.Value = CurrentStage.Value + 1
