Ergodic TVI custom indicator downloaded from this forum...comes up blank on screen

 

Hi!

Being a newbie at programming (MQL4), I've downloaded and installed a few indicators from this site (Ergodic Osc and the TSI) and they are working fine. But the Ergodic TVI is not. I do get a window on the chart below the candles (I have volume beneath the candles in the same window as the candles) but it is blank...that is no graph whatsoever. I assume I must be doing something incorrectly for this particular indicator (no problems with the others, however). If anyone has an idea why this is happening, please let me know. Thanks for your help in advance.
