difficulty in summing up the values of the excel VBA form

[sayedqurrat]

I have created a marksheet userform through excel. And have created a command button "add record" on the form. In the form I have labels of different subjects with textboxes alongside and also have a label of "total"(to sum up the marks of all the subjects). And now I am finding a difficulty in writing a code for the "total "...
What I want is that, when I enter the code in the "add command button" I want to write the code for the "total label" also in the same command button...so that when I run my program...the entire record including the total is displayed on the excel sheet...I HV learnt a lot of things from your links...please help me out with this...
