Hello naveen ,

To correct the provided Visualforce markup, you need to make a few adjustments to properly display the table and bind it to the appropriate controller or extension. Here's the corrected code:

You need to specify the correct value attribute for the apex:pageBlockTable, which should be a reference to the list of Transaction records you want to display.

For each apex:column, you should use the value attribute to specify the field API name that you want to display in that column.

Use the apex:inputField tag for editable fields, like Name and Qty, and use apex:outputField for non-editable fields, like Product.

Assuming you have a custom object named "Transaction_c" with fields "Name," "Productc," and "Qty_Sold_c," and you have a list of Transaction records in your controller or extension named "transactionsList," here's the corrected code: 
<apex:page standardController="Transaction__c">
    <apex:form>
        <apex:pageBlock title="Purchase Order">
            <apex:pageBlockTable value="{!transactionsList}" var="transaction">
                <apex:column headerValue="Name">
                    <apex:inputField value="{!transaction.Name}" />
                </apex:column>
                <apex:column headerValue="Product">
                    <apex:outputField value="{!transaction.Product__c}" />
                </apex:column>
                <apex:column headerValue="Qty">
                    <apex:inputField value="{!transaction.Qty_Sold__c}" />
                </apex:column>
            </apex:pageBlockTable>
        </apex:pageBlock>
        <apex:commandButton value="Save" action="{!save}" />
    </apex:form>
</apex:page>
With this corrected code, you should be able to create a Visualforce page named "Purchase Order" that captures transaction line items with their Name, Product, and Quantity in a table. Make sure to adjust the controller or extension logic to handle the creation and manipulation of the "transactionsList" appropriately.

If this helps , please mark this as Best Answer.
