i need modification for this code as fast as possible

[cool_guy4ever15]

Hello every body.

am working on sms remote control project am using ericsson t290i and AT89s52 microcontroller and Microcontroller Kit.

when i send to the mobile sms contain "SS1on" it switches on the led no.1
then delete the sms after reading it automatically,then when i send "SS1ofn"
it switches off the led no1 then delete the sms .when i send "SS2on" it switched on the led no.2. the prob is when now i send "SS2ofn" it doesn't respond to the recieved sms and stops delting it and it doesn't appear on the lcd.i don't know wht to do so plz i want some one to modefy me the cod i attached in that post as fast as possible plz.

Note:

i think that the mobile stops reading the incomming sms's after the third sms it works well before that.

here is the code plz i want the modification sent to me as" lcd.c" i just wanna that file and i will rebuild it then burn the hex.
