Excel 公式检查文本第 2 部分

Question

Adding on to a question I asked yesterday, I am getting a "There's a problem with this formula" error in Excel.

I am using the following formula:

=IF(OR(AD9834="In progress",BB9834="",ROUND(BW1-AI9834,0),IF(AD9834="Reopened",ROUND(BW1-AP9834,0),(BW1-AI9834,0))))

I just need a second set of eyes because I am not seeing where the error is located.

Answer 1

Solution is quick and I cover this in first few lines that follow. Have also expanded by highlighting a few tips/tricks I use to audit my own (and my teams'/others' excel workbooks/models etc.). Trust in order (flag any Qs you may have in this regard as req.)..

Ta,

Summary of changes

1. Include bracket to close OR statement in first / outer IF statement
2. Include 'Round' in final part of function

Corrected Function:

=IF(OR(AD9834="In progress",BB9834=""),ROUND(BW1-AI9834,0),IF(AD9834="Reopened",ROUND(BW1-AP9834,0),ROUND(BW1-AI9834,0)))

Auditing tips/identification routine

When auditing / validating a function (especially long ones like this), I like to:

(a) Use function assistant popup window

• Click on each of the components of the function that appear in the little popup window when you enter the function
• This will highlight the corresponding part of the code in the function window.

I'm talking about this popup in your case:

You can drag it around the window, eg here I've placed at the bottom of the function window / toolbar:

For instance, in screenshot below, I've clicked on 'logical test' part of the IF statement, and could immediately see where you've gone wrong - as the "logical test" component of the IF statement corresponded to your entire equation - ie you've obviously missed a comma or bracket somewhere to separate out 'value if True' and 'value if False' components:

(b) Simplify by creating 'test' function

Inserting the first bracket, and simplifying for the moment by referencing cells A1, B1 instead of A100095, B214032 etc., I repeat the 'click component' routine for the next sub-function (your OR statement).

(c) Evaluate sub-functions within function:

I also like to highlight the various 'sub-functions' and evaluate them (press f9 - but be careful not to press 'enter' as it will embed/overwrite test function, instead press ctrl+Z to reverse the evaluation) within the function window/toolbar to see which ones are working/broken.

Doing so simplifies checking the long function you have to something that looks like this:

ie step 1: highlight sub-function like the OR statement: *

step 2: press F9 to temporarily evaluate:

step 3: repeat for each 'sub-function'

As I've fixed this item, no errors upon evaluation, I move onto next sub-function and eventually end up with an error when trying to evaluate your final if statement:

step 4: repeat above for each sub-function of 'parent' sub-function

• In this case, your 2nd IF statement, comprising 'children' = logical test, true / false sections of IF statement)... step 4: cancel out by pressing escape

Doing so quickly allows me to identify your missing 'round' statement (I imagine it's this you intended to have) right at the end of the function.

(d) Check brackets Penultimate step is to check opening and closing brackets - to ensure you have applied these correctly. Don't go with Excel's auto-fix proposal that sometimes pops up:

(e) Apply changes to original function as required

Finally, I manually adjust the original function according to the errors identified using the 'cut-down' temporary 'test function' created above.

This leads to the following proposal for you to conveniently 'copy and paste' in the relevant / applicable cell:

(see up top)..
