Unable to use delay with custom variables

So im making this on sneak teleport raycast armor thing, but when i hold sneak i find that i zoom really fast really far because im teleporting every tick and when i tried to use the "wait [] ticks then on server-side do" does not support custom variables and have no idea how to do it without them.

I really (even if there is a fix) that mcreator adds a "wait [] ticks" blocks which works with anything
