Hi all,

I am trying to increase a counter based on a record match. I first initialize the counter to 1. If there is a record match, I want to increase the counter by 1 else set the counter to 1.

For instance, if there are five records matches in a row, the counter would be equal to 5. Below is my code. Currently, the stage variable only increases to 2 and repeats 2 for every record match after that, so it is not increasing after 2. What is causing this?
I have also tried the below, which results in record matches returning only zero:
Let me know if anyone needs more information.

Thanks in advance.

The first code should work if it is the derivation expression for the stage variable svGroupRecordsIdx.

The second code will not work because you have tried to use an assignment statement, but it's actually treated as a Boolean test condition.

Thanks for the reply.

Not sure what your exact response was, since I am not a premium member. However, I believe to understand that we cannot use assignment statements within stage variables.

I will try and see if there is a workaround.

A derivation is an expression who's derived value is automatically assigned to its associated variable. You cannot do direct assignments in any derivation.

Use the given expression below. It will work.

If svMatchCheck = 1 Then
(svGroupRecordIdx + 1)
Else
1
