Hi @PeterJennings
It seems like you want to check for a specific column change for sharepoint list.
If yes, then the whole flow is for your reference:
In my case, I check changes for a column named ‘Description’. The steps to complete this are a little complicated and I’ll explain to you in details.
If the change for the column value is equal to ‘Booked Out’. Then delay 5 days and check the item again, if it’s still ‘Booked Out’, then send an email.

For the ‘Condition’:
It’s used to check whether the item is created or changed. If the item is created, then exists flow. If the item is changed, then go on with the flow.

For the ‘Initialize variable to hold item ID’:

For the ‘Send an HTTP request to SharePoint’:

_api/web/lists/getbytitle('test1')/Items(@{variables('varID')})/versions
For the ‘Parse JSON’:

The ‘Schema’ is copied from the outputs of ‘Send an HTTP request to SharePoint’, which means before adding the ‘Parse JSON’ action, you need to run the flow and get the outputs of ‘Send an HTTP request to SharePoint’.
For the ‘Initialize variable to hold value to be compared’:

The expression used:
body('Parse_JSON')?['d']?['results'][1]['Description']
This expression is used to get the column value whose version is immediately before the current version.
Here, my column field name is ‘Description2’ though the column display name is ‘Description’. You can find the column field name in URL of the column as below:

For the ‘Condition 2’:

The condition 2 is used to check whether the previous version of the column value is equal to the current version of the column value.
If no, then it means that the item whose value has been changed is that of the ‘Description’ column.
Then go on with condition3. If the current value of the ‘Description’ column is equal to ‘Booked Out’, go on with ‘If yes’.
For ‘If yes’ in ‘Condition3’:

Delay 5 days and get the item again.
If the column value is still ‘Booked Out’, then send an email.
