i have two columns in my sharepoint list
[Cluster Name] and [Host Name]
I wanted to implement a calculated sharepoint data for a [Cluster Name] column like if the field is blank it needs to have the first 3 characters from Hostname with an suffix of STANDALONE at end, can any one help me out on this, here's what i have till now, but when i try this it gives an error
=IF(ISBLANK([Cluster Name]),(UPPER(LEFT([Host Name],3))-STANDALONE),)
