Substitute just ONE from a list

[serp]

I have a text field. 20 users.

Each time a guy is looking one branch we paste the branch's id, per.ex, 010062.

So if a second guy go to the same branch:

010062

010062

040033

etc

Also I have a script if (Patterncount (x;010062) > 2; block entrance; allow entrance)

I would like to remove this "id branch" after 1 guy "leaves" the branch, but just ONE "010062" not all. So 2 guys in 010062, after 1 goes out, there is still ONE 010062, not two!!

How I can manage that?

Set Field [textfield; Replace( textfield; Position( textfield; "010062"; 0; 1 ); 7; "" )]

Set Field [textfield; Replace( textfield; Position( textfield; "010062"; 0; 1 ); 7; "" )]

Look in the online help for information regarding the Replace and Position functions. You'll see that since Position has an occurrence parameter of 1, it will find and replace only the first instance of "010062" in textfield. Replacing 7 characters allows the trailing
