Hi?

I'm a user of Brilliant database 10.5 and have a question for everyone please.

Please i need help on how to Subtract a field's value in a form from another field value in a

different form based on a rule that if both forms each have a field that has a common

value, then the subtraction holds. e.g

if in form "A", there are two fields namely [label] having a value of DER45, and a field called

[Figures] having a value of 5600. And if in form "B", there are also two fields namely [label]

having a value of DER45, and a field called [Figures] having a value of 4500.

So what i want to achieve is to say that because both forms have a common value for their [Label]

fields, i will then subtract the value of [Figures] in form "B" from [Figures] in form "A" to give the answer in another field called [Difference] on form "B".

I will be grateful if promptly replied. Thanks a lot.
