I try the way you told me but getting the following error

# ./robot.ksh
++ TRY=1
++ word1=
./robot.ksh: line 16: syntax error in conditional expression
./robot.ksh: line 16: syntax error near `-a'
./robot.ksh: line 16: `while [[ TRY -lt 4 -a "$word1" != "slot" ]]'
#

2. Please use code tags. It's no fun reading such scripts with no formatting. I edited your post - it now has code tags.
3. Please try it again with doube square brackets like:

Code:

while [[ $ERRORCODE -gt 0 -a $TRY -lt 4 ]]

4. Also to be sure maybe start using variables in this form:

Code:

${VAR}

5. Use set -x to debug your script
6. Use echo on your variables to debug your script
