how can I create an id for data or records in xlsform.
I do not understand the question.
Look at the sample form and XLSForm documentation to get an understanding
of the tools and how you use them.

for example: I want to create a xlsform containing student record and I
want each student to have an id (identifier) that is unique and which will
be created by me.
how do I do this?

> >Hello Mercy,
Did you think of using concat(val1,val2,...) to generate a concatenate of more than one variable as your student ID can be Faculty, Degree, DOB and so on to generate a Unique identifier or use the uuid() function to generate a random key for you (I won't recommend this as you won't have control on what is generated)

e.g., concat() will probably be useful.
See the sample XLSForm for how to define a calculated field.

do you have another approach to answer the question?
thanks, I will work on it ..
I visited the link above and I try using the concat function but after
uploading the xlsform, the id did not generate itself automatically.
can you show me how to use the concat function .
I used this and am not sure if it is correct. calcualate="concat(/data/staff_serial_num,'
with id: ', /data/age)"

> >> >Hello there,
The concat function can be used anywhere, constraint, relevant and
calculation. based on your email it looks like you made a calculate type
variable which is totally fine but remember calculate variable are ready
only therefore has to be always used together with other variables like
tex, integer and more to read their content.
Below is the very basic yet useful example of concat and lengt functions
type name label constraint calculation read_only required integer
ID_V01 What is you random ID? .>=1001 and .<=1999 1 text ID_V02 What are
your names initials? string-length(.)>=2 and string-length(.)<=3 1
calculate ID_V03 concat('EID-',${ID_V01},'-',${ID_V02}) text
ID_V04 You
have successfully generated the new employee ID as: ${ID_V03}
concat('EID-',${ID_V01},'-',${ID_V02}) 1 1
hope you find it useful
Cheers
