hi,

yes i need sample, but i want to run this function or procedure many times for many defrent textboxes at my form.(i don't know how)
ex..
thisform.text3.value=thisform.text2.value-thisform.text1.value
thisform.text6.value=thisform.text5.value-thisform.text4.value
.
.
.
and how ican sum the times from mytextboxes as thisform.text10.value=thisform.text3.value+thisform.text6.value

and thisform.text12.value=thisform.text10.value*$11.9.

if you think or feel this is too much forget it.

thank you very much.

best regards
