EFS Study Title Question

[george65202]

In the following study, a McClellan Oscillator that I downloaded from here somewhere... it displays

"McClellan Oscillator(Expotential,Off)"

in the upper left corner of the study.

I want to make it just say

"McClellan Oscillator"

without the (Expotential,Off) part.

Can somebody look at the following code and advise me what needs to be changed? Thanks!!
