Son Tung Mai difference between 2 picklist value time fields
hi everyone
i have 2 picklist fields for time values of a course sessions with the format including AM, PM as below
1. start time (i.e. 6:00 AM, 6:15 AM, etc)
2. end time (i.e. 6:00 AM, 6:15 AM, etc)
i want to create a formula field to work out the difference between the values selected for these 2 fields, to display the duration scheduled for a session
for example, if start time = 6:00 AM and end time = 8:00 AM, the session duration will be 2 hours
i have tried different syntax but still going nowhere
the current one im using is ((TEXT(End_Time__c) - TEXT(Start_Time__c))*1440)
but it giving me an error " Error: Incorrect parameter type for operator '-'. Expected Number, Date, DateTime, received Text"
can anyone help please?

If PM convert to 24 hour equivalent (I.e add 12 to hours) 6.15 = 18 x 60 + 15 = 1095
Then subtract to get the difference and divide by 60
1095-570= 525 / 60 = 8.75
can you please collaborate?
