Excellent. Just done some validation checks - I understand your variables but don't understand how you can embed 4 variables. You have managed to remove the OR variable?

<div>
Now you have 2 cases:<br />
1. AND: -1.5 &lt;= D13 &lt;=0, 0 &lt;&nbsp;D14 &lt;= 2 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;- calculate S<br />
2. All other cases &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;- S = 0
</div>


Now you have 2 cases:
1. AND: -1.5 <= D13 <=0, 0 < D14 <= 2          - calculate S
2. All other cases                                              - S = 0

Not sure my logic is correct with this, but I thought i would give it a go. I have used an IF OR statement and then on the true variable embedded an IF AND statement. Within the attached spreadsheet, cells D13 and D14 I check 1st for validity - in the example I have given, the values fall within the true range so should then calculate the exponential - this is not happening. In cell G16 I have checked what I believe the output should be for the below. Within the worksheet I have embedded an image of the calculations I am trying to automate. i decided to start with those circled in red with 1 and then check 2....<br />
<br />
=IF(OR(D13&lt;-1.5,D14&gt;2),0,I<wbr />F(AND(-1.5<wbr />&lt;=D13&lt;=0,0<wbr />&lt;=D14&lt;=2),<wbr />D16*EXP(D1<wbr />7*D13),0))<wbr /><br />
<br />
Thanks in advance, Paul<br />

Issues with 'If' statement - excel

Microsoft Excel topics include formulas, formatting, VBA macros and user-defined functions, and everything else related to the spreadsheet user interface, including error messages.

Microsoft Excel

Microsoft Office is an integrated suite of applications that includes Outlook, Word, Excel, Access, PowerPoint, Visio and InfoPath, along with a number of tools to assist in making the individual components work together. Coding within and between the projects is done in Visual Basic for Applications, known as VBA.
