incatt modifiaction

Hello,

Can someone help met with the following lisp?

iam using a lisp (incatt) to increase a attribute of selected block. this works perfect.

I want to add a function. in the blocks there is also an attribute with the tag "room-nr".

iam using the lisp for coding safety symbols/blocks. I like to add the function room-nr to the lisp. So when i run the lisp, it asked for the room number and the rest stays the same. It increase the number ("TEXT1" tag) and adds the room number to the block. By the next run it prompts again with the room number and starts with the previous number. But NO auto count on thr room number part.
