Using If and statements in excel 2007 for multiple criteria | General Excel Questions & Answers | Excel Forum

Help please using excel 2007

I am trying to set up a formula that will calculate a value based on multiple criteria.

So far I have set up 4 separate "if" statements but I need to combine them into one that will provide an amount based on conditions.  Each individual if statement works ok and calculates correctly.  If anyone can help I would be extremely grateful.

=IF(AND(A37="Unit T",C37="Repair",OR(D37="Hoist",D37="shower",D37="bath",D37="recliner",D37="Pillow",D37="cushion",D37="Lift",D37="Station")),G37*40.96+J37*40.96+N37+O37*0.5,"")

=IF(AND(A38="Unit T",C38="call-out",OR(D38="Hoist",D38="shower",D38="bath",D38="recliner",D38="Pillow",D38="cushion",D38="Lift",D38="Station")),G38*61.01+J38*61.01,"")

=IF(AND(A39="Unit T",C39="Repair",OR(D39="Bed",D39="Mattress")),G39*61.01+J39*61.01,"")

=IF(AND(A40="Unit T",C40="call-out",OR(D40="Bed",D40="Mattress")),G40*80.7+J40*80.7,"")

In summary there are 4 different charge rates depending on whether it is a repair or call out and the type of call out e.g. pillow etc.

Is there a way of combining all of the above into one workable if statement?

Thanks in advance
