My sensors don't work

I tried installing the sensors on the EDU and test them out, but the coding doesn't seem to be working


this is what i have:

if c_sensor1=1 then c_p1_y=1

what's wrong with this code if it keeps telling me that it expects a label

A couple of problems: Both c_sensor1 and c_p1_y are CONSTANTS used in initialization to set up communications with the master microprocessor. You're not going to be able to SET c_p1_y. You should use if sensor1=1 then p1_y=1 as SuperDanman suggested.

Also, since you are using PBASIC v2.5 syntax (if ... then ... statement) rather than v2.0 (if ... then ... label), you need to enable 2.5 syntax by including a '{$PBASIC 2.5} directive. (If 2.5 syntax had been enabled, the error message would have said: "Expected a label, variable, or instruction" instead of "Expected a label".)
