Thank you for giving my help again. Now I almost have already understood this function, but I want you help me the last time. Do you help me translate the follow sentence ¡®s means detailed?
Will there be found the ¡®divider¡¯ in ¡®formadata¡¯? If found, I want to know why will be found two time?

divider=leftB(formdata,clng(instrb(formdata,bncrlf))-1)
dataend=instrb(datastart+1,formdata,divider)-datastart

I used the follow sentence to display some information
Response.BinaryWrite formdata ¡®one
Response.write ¡°<br><br><br>¡±
Response.BinaryWrite mydata ¡®two

I found that use one input more information than two. I found that it is different between the front excrescent and the back excrescent. Now that it is different I do not know how to translate the sentence ¡®dataend=instrb(datastart+1,formdata,divider)-datastart ¡®? I do not know how to find the back excrescent information?
