Counting enum list entries

[Raju_Tadepally]

Hi friends

l am developing a small app, where i need to count number of entries / selection a user does for Enum list in a column Named: “Application ID” while entering the values in a form.

i tried to use the following expression:
count([_thisrow].[Application ID]) , However i couldn’t get the count.

Issue -2 :
i have created a column "Allotted Time " type “duration” & i wanted to divide the value entered in this row with Number of counted entries in column “ID” which is pure number. However it is not going through.

Issue 3 :
i have a different forms BBF1,2,3 Etc. & a particular duration for each form in "Standard Manhours " column for that activity as below

in the form entry , when the specific form is selected , i wan the particular duration to be displayed without making any selection. how to get this done?

thanks in advance.
