Hello all
Question


How do I add a percentage to a field and show me another increase in field
Example
If the price was increased to 70 and 30%

70 × 30
------------- = 21
100

70 +21 = 91

x + (x * 30 / 100)

or

x * (1 + 30/100)

Thank you
Did I can control the percentage is fixed and Make it through the field

[June7]

Don't understand the question.

If the percentage varies, what field has the percentage value?

Why are wages less than $1.00?

[azhar2006]

Yes, less than one dollar
It cents

My question was
Is it possible to control the value of%
I mean
There are goods that we take 30%
The Other 20%
The Other 50%

[June7]

Yes, you can. Is there a table of goods with a field for the percentage? Include that table in the query and link on the PK/FK fields for the goods ID. Just another data relationship.
