Do loop issue

good evening everyone,

ok so i have a label(1) with a value of 10 in it

i input a value through an input box of say 100 which goes to label(2).

label 1 and 2 get added together and result is shown in label(3)

i then run a loop on label(1) +10 untill it reahes a value of label(3)


this all works fine but my poblem is it happens too quickly. as soon as i input the value to be added....bam, there it is in label 3

is there anyway to slow down the loop i guess is what i am asking.

thanks in advance for any help
