Cells not updated automatically

[CS Chia]

I have a formulas that doesnt automatically compute the formula there i
a change in one of the input

There are 3 tabs, A, B,

A is the tab which has the SUMPRODUCT formulas
This formulas reference to data in tab B

Tab B has a column which takes data from Tab C to generate an output
This output will be used by tab A

I realised that if I update the information in tab C, there formulas i
tab A doesnt automatically get updated

I search in the internet and someone mentioned that this could be due t
the fact that tab A doesnt know that they need to recomputed when ther
is a change in tab C

Anyone know how to make tab A re-compute the data when there is a chang
in tab C

I have attached the sample mentioned here in this tread
The sample is working but not at my actual excel

Not sure why is it not working in my actual cell
Any way to push the formulas in tab A to auto-update when there is
change in tab C

Updates
I realised that if I do a Ctrl + Alt + Shift + F9, the cells will b
updated
However, is there any thing I can do to make it auto-updates without th
need to manually refresh the table

Many thanks for the assistance

Uh.., is Calculation set to 'Automatic' in the Options dialog?

Yes, it is set to automatic

This is the formula:
=SUMPRODUCT(--('Tab B'!$C$3:$C$3010='Tab A'!$A$4),--('Ta
B'!$D$3:$D$3010='Tab A'!$B$4),--('Tab B'!$E$3:$E$3010="YES"),('Ta
B'!M$3:M$3010))

It was working when the formula is this:
=SUMPRODUCT(--('Tab B'!$C$3:$C$3010='Tab A'!$A$4),--('Ta
B'!$D$3:$D$3010='Tab A'!$B$4),('Tab B'!M$3:M$3010))

--('Tab B'!$E$3:$E$3010="YES") was not there.

In tab B, the column E has a formula
=IFERROR(UPPER(INDEX('Tab C'!$B$6:$D$36,MATCH('Tab B'!$B4, 'Ta
C'!$B$6:$B$36,0),3)), "")


The moment this --('Tab B'!$E$3:$E$3010="YES") is added, the formula
doesnt automate update when there is a change in tab C.


Please help.
Thanks
