If you have ever tried to use Excel and received an error message saying "empty cells trigger error," then you know how frustrating it can be. This error can occur for a number of reasons, but the most common cause is when there are empty cells in your data range. When Excel encounters empty cells, it assumes that you want to perform a mathematical operation on them, but since there is no data in the cell, it cannot perform the operation and returns an error.

There are a few ways to fix this problem. The first is to simply delete the empty cells from your data range. This can be done by selecting the cells, right-clicking, and selecting "Delete." Another way to fix this problem is to fill in the empty cells with a value. This can be done by selecting the cells, right-clicking, and selecting "Insert." Finally, you can use a formula to ignore the empty cells. For example, if your data range is A1:A10 and you want to sum only the non-empty cells, you can use the following formula: =SUMIF(A1:A10,"<>")

If you receive this error message frequently, it might be a good idea to check your data ranges for empty cells before performing any operations on them. This will save you time and frustration in the long run.
