Hi group. I am very inexperienced in using MS Excel however I am trying to develop a simple spreadsheet which will do a calculation that I have to do on a regular basis. I have several questions which I hope that the people within this group can kindly help me with.
Ok, here goes. 1 - I want a cell to contain the calculation (I55*3600)/I54 is the syntax simply =(I55*3600)/I54 I've currently got the formula =SUM(I55*3600)/I54 in this cell. I have believe that this formula is incorrect. 2 - The cell where the above formula is located contains the message #DIV/O! until a value is input into another cell. How can I stop this error message from being displayed? 3 - I want cell A10 to look at cell A9. The value of cell A10 will vary depending on what value is in cell A9. Basically I want a formula in cell A10 which says: If A9 is less than or equal to .5 then A10 = 2 but if A9 is greater than .5 but less than or equal to .8 then A10 = 3 or if A9 is greater than .8 then A10 = 4 4 - I want the operator of the spreadsheet to be able to input information into some cells but not be allowed to alter the data in other cells. How can I protect cells to prevent the user of the spreadsheet from altering their content? Hope someone can help me out within the group. TIA.
