quebasic2 is correct. You can't simply tell a sub to specifically goto to a line lable in the main (unless, if memory serves, it is an error trapping code.)
When you CALL sub-name the next line is not execuited until the EXIT SUB was reached. So my suggestion is to create a "global" variable; in the "sub"...change it to something else like gblGoto10 = -1, THEN in the line following the "call" add a validation to take you to LineLable 10.
The only other option is to post some code for us to make suggestions.
