I have a spreadsheet filled with formulas that depend on a value being entered into A2, A3, A4, etc... So column A starting at A2 is where I will manually input a number and the formulas I have in columns B, C, and D will import information from another sheet based off what is put in column A. In column D the formula I have to import data is =IFERROR(VLOOKUP(A2,Master!C:M,11,0),""). This will import another number. Additionally in column D, I have conditional formatting that will return a red, yellow or green light based off the rule I have in place. Everything works fine, the only problem is that column D has a green light all the way down even without a value being placed in column A. I would like to find out a way to keep the cells in column D blank until a value is entered in column A. Also, if I go back and delete the value in column A, I would like the corresponding cell in column D to go back to blank as well. Is this possible or am I asking too much from Excel? Thank you in advance for your help!
