The intersection operator is a space character that separates references in a formula.c. =Sum(A1:A2 C3:C5) returns the #NULL error because the two ranges do not intersect.d. =SUM(A1:F1 B1:B10) will return the correct reference.Now I did grab these from a website but I am familiar with all of these problems and fixes (it was just easier to take it from there as it was formatted and explained better than I probably would have explained it). > Great Ideas there Kyle. It wasn’t until someone else posted that I was able to post in there because new message isn’t showing up for me on here Marion. Errors in Excel usually has something to do with the formula or format being incorrect. I have seen some where it’s been extracted in reports that the fields has to be extended to keep from getting #### in the rows or columns. Another is when it says error from trying to type in a wrong format for that formula that’s in place. Generally correcting that format will straighten that issue out. I don’t use it as much as some people, but Excel is nice to have if you know how to create the formulas to go along with it. The “tell me what you want to do” utility in Excel 2016 is awesome > Thanks for sharing Kyle. I was just looking at this same source to use for the assignment. I agree that it is formatted and explains each error, cause, and resolution very well. I myself have had limited experience in using Excel but recognize having seen these error in the past. Just this morning while trying to start on this weeks assignment I ended up with the ##### error and got frustrated because I could not remember what the cause or resolution was in that moment. Therefore, I find doing the assignment on going over each of these errors, causes, and resolutions will be useful for when I come across an error in Excel in the future. > Wow! That is a great list Kyle! I have seen many of those when working with Excel. Another one I have seen is when trying to paste into a spreadsheet and the message says “cannot change part of a merged cell”. Here is a great explanation of why it happens and how to fix it:”Cannot change part of a merged cell. This message appears when you try to: Paste a mismatched range of cells into a merged cell. For example, if you merge eight cells and try to paste a range of six cells onto the merged cell, the alert appears. To fix this problem, copy and paste a range of cells that matches the size of the merged cell. Cut or delete a row or column that includes a merged cell. Clear the contents of a row or column that includes a merged cell. Apply a filter to a column containing a merged cell, and then try to delete the merged cell. To fix problems with cutting or deleting, split the merged cell and repeat the cut, delete, or clear operation. To split merged cells: Locate and select the merged cell. On the Formatting toolbar, click Merge and Center. -or- On the Format menu, click Cells, click the Alignment tab, clear the Merge cells check box, and then click OK. Note When you split a merged cell, Excel writes the data from the merged cell into the upper-left split cell and leaves the adjoining split cells blank.” ONLY CHOSE 5 Errors to Discuss
