Here are some of the Comments we have received for our Videos:
”I cannot believe how painstaking and patient this was. I needed a tutorial with every keystroke explained. EVERYONE else wants to breeze through this stuff. For context, I’m blind, and I followed this entire thing completely. I don’t know if blind people are who you had in mind, but this was phenomenal. I want you to teach me everything now! Now I’m wondering about using structured references in formulas like COUNTA and COUNTIF where I reference a whole column At least I have the confidence now to take a shot at it.”
“You are wonderful at explaining. Thank you!”
“Simple and Genius – You solved my problem just like that. Thank you.”
