<div>
I put the following formula in Hours worksheet cell D2 and copied it down and across.<br />

<pre><code id="code-20-42969517-1">=SUMIF(INDIRECT(&quot;'TIME &quot; &amp; TEXT(D$1,&quot;m-d&quot;) &amp; &quot;'!D:D&quot;),$A2,INDIRECT(&quot;'TIME &quot; &amp; TEXT(D$1,&quot;m-d&quot;) &amp; &quot;'!M:M&quot;))</code></pre>
If you don't want to look at all the zeros, then consider using a Custom number format like #;-#;-;@ or possibly #;-#;;@<br />

PERFECT AND AWESOME! &nbsp; Thank you Byundt

I probably should have pointed out that the formula (and macro) rely on the worksheets being named exactly according to the pattern in the sample workbook. Any deviations in the worksheet name (perhaps an extra space, leading 0 in the date, missing hyphen, etc.) will result in a column of #REF! error values.

I have multiple timesheet tabs for each week until the end of the year. &nbsp;Each worksheet the user will select a project number and put down hours against that project number. <br />
<br />
I populated two tabs Time 10-21 and Time 10-28 with some project numbers and hours. &nbsp;What I'm asking is on the &quot;hours Tab&quot; that the hours are being added from &nbsp;each tab. &nbsp;See hours on the &quot;Hours Tab&quot; for examples.<br />

I have multiple timesheet tabs for each week until the end of the year.  Each worksheet the user will select a project number and put down hours against that project number. 

I populated two tabs Time 10-21 and Time 10-28 with some project numbers and hours.  What I'm asking is on the "hours Tab" that the hours are being added from  each tab.  See hours on the "Hours Tab" for examples.
