Need help getting fibonacci level, using the string variable

[Aesen Noah Remolacio Perez]

My idea is: i want to be able to manually place my fibonacci on a chart and have the EA send me an email notification when the bid price hits a specified level(example: 50%, 61.8%,etc...) in the EA. But my only problem is i'm having trouble getting the fibonacci levels while using the string variable. Do i have to use objectcreate for this idea instead? Awaiting your advice on the matter, please and thank you in advance
