I have been encountering the error "Undefined local variable 'x1'" error while using the following trim script.[color=blue:3ca5a6763b][size=9:3ca5a6763b]#ap_subtrim_v_1.cl by Paul Iverson
#the purpose of this script is to remove possible bad pixels at the edges of the imagesprocedure ap_subtrim_v_1 (xsmall,xlarge,ysmall,ylarge)string xsmall {prompt = "Minimum x value"}

string ysmall {prompt = "Minimum y value"}
string ylarge {prompt = "Maximum y value"}begin

int xlen, ylen

[/size:3ca5a6763b][/color:3ca5a6763b]Interestingly enough, I have used this syntax to call a prompt in another script and it works fine.Any ideas?

Quick guess: The 'end' statement following the 'string' variable declarations instead of being the last line in the script. -Mike

The problem was actually in my login.cl.
