# Easy Language Error #1

Can anyone help me fix a code Bard provided to me that TS won’t accept? Error 1; Description: unknown identifier; Location: Camarilla; Line: 2

// Retrieve previous day’s high, low, and close prices
high_prev = GetPreviousDayHigh(Close, 1)
low_prev = GetPreviousDayLow(Close, 1)
close_prev = GetPreviousDayClose(Close, 1)

// Calculate the pivot point (PP)
PP = (high_prev + low_prev + close_prev) / 3

// Calculate support levels (S1, S2, S3, S4)
S1 = (PP - high_prev) + 2 * (PP - low_prev)
S2 = PP - 2 * (high_prev - low_prev)
S3 = PP - 3 * (high_prev - low_prev)
S4 = PP - 4 * (high_prev - low_prev)

// Calculate resistance levels (R1, R2, R3, R4)
R1 = (2 * PP) - low_prev
R2 = PP + (high_prev - low_prev)
R3 = PP + 2 * (high_prev - low_prev)
R4 = PP + 3 * (high_prev - low_prev)

// Plot the levels on the chart using appropriate EasyLanguage plotting functions
